Expert Google Searching Part 1: Using Boolean operators and phrase searching [Image of google.com search box]
Audio: How can you make Google work better for you when you're searching? Here are a few tips and tricks to get you started. Let's say we're doing research on the impact of multiracial people & culture in America. We're just getting started, so we'll type "multiracial" into the Google search box.
[Image of search results]
Audio: Notice that we are getting all kinds of results using this search -- from Wikipedia, to a site called "blackflix.com," to even some government websites thrown in there.
We can do better. Let's try adding some keywords to narrow our search -- I'll try multiracial AND culture
[Image of search results]
Audio: When you type multiple words into the search box, Google will look ONLY for those results that have ALL of your keywords. In fact, Google does this by default so you don't even have to type "AND" if you don't want to. Even just adding one keyword has given us way fewer results (even though there are probably still more than we want). You can keep experimenting with different keywords in different combinations to see how Google will work for you.
You can also broaden your search by asking Google to look for synonyms or related ideas using the word "OR." Instead of just "multiracial," I'll try looking for "multiracial" OR "biracial."
[Image of search results]
Audio: This search will find anything that has either the word "multiracial" OR "biracial" (or both) AND also "culture." Notice that by adding this alternate term, we have cast a wider net and so we are getting more results than our last search.
Lastly, you can use Google to search for more complicated words and phrases using quotation marks to conduct a "phrase search." Let's try using the specific phrase "multicultural identity" in our search this time. [Image of search results] Audio: Ok, so this search found results that have the both the word "culture" AND the exact phrase "multiracial identity" -- it will not find instances of the word "multiracial" in one part of the website, and the word "identity" somewhere else! This is a handy search for compound words, names, or phrases, but remember that once you put quotation marks around it, Google will look for that EXACT string of letters -- it will not find misspellings of that phrase for you, like it usually would in other searches. So when using phrase search, make sure you double check your spelling! Try experimenting with different combinations of AND, OR, and phrase searching to make the most of your Google search.

So a few weeks ago, a friend of mine gave this toy car to his 8-year-old son. But instead of going into a store and buying one, like we do normally, he went to this website and he downloaded a file, and then he printed it on this printer. So this idea that you can manufacture objects digitally using these machines is something that The Economist magazine defined as the Third Industrial Revolution.
Actually, I argue that there is another revolution going on, and it's the one that has to do with open-source hardware and the maker's movement, because the printer that my friend used to print the toy is actually open-source. So you go to the same website, you can download all the files that you need in order to make that printer: the construction files, the hardware, the software, all the instruction is there. And also this is part of a large community where there are thousands of people around the world that are actually making these kinds of printers, and there's a lot of innovation happening because it's all open-source. You don't need anybody's permission to create something great. And that space is like the personal computer in 1976, like the Apples with the other companies are fighting, and we will see in a few years, there will be the Apple of this kind of market come out.
Well, there's also another interesting thing. I said the electronics are open-source, because at the heart of this printer there is something I'm really attached to: these Arduino boards, the motherboard that sort of powers this printer, is a project I've been working on for the past seven years. It's an open-source project. I worked with these friends of mine that I have here. So the five of us, two Americans, two Italians and a Spaniard, we — (Laughter) You know, it's a worldwide project. (Laughter) So we came together in this design institute called the Interaction Design Institute Ivrea, which was teaching interaction design, this idea that you can take design from the simple shape of an object and you can move it forward to design the way you interact with things. Well, when you design an object that's supposed to interact with a human being, if you make a foam model of a mobile phone, it doesn't make any sense. You have to have something that actually interacts with people. So, we worked on Arduino and a lot of other projects there to create platforms that would be simple for our students to use, so that our students could just build things that worked, but they don't have five years to become an electronics engineer. We have one month.
So how do I make something that even a kid can use? And actually, with Arduino, we have kids like Sylvia that you see here, that actually make projects with Arduino. I have 11-year-old kids stop me and show me stuff they built for Arduino that's really scary to see the capabilities that kids have when you give them the tools.
So let's look at what happens when you make a tool that anybody can just pick up and build something quickly, so one of the examples that I like to sort of kick off this discussion is this example of this cat feeder. The gentleman who made this project had two cats. One was sick and the other one was healthy, so he had to make sure they ate the proper food. So he made this thing that recognizes the cat from a chip mounted inside on the collar of the cat, and opens the door and the cat can eat the food. This is made by recycling an old CD player that you can get from an old computer, some cardboard, tape, couple of sensors, a few blinking LEDs, and then suddenly you have a tool. You build something that you cannot find on the market. And I like this phrase: "Scratch your own itch." If you have an idea, you just go and you make it. This is the equivalent of sketching on paper done with electronics.
So one of the features that I think is important about our work is that our hardware, on top of being made with love in Italy — as you can see from the back of the circuit — (Laughter) is that it's open, so we publish all the design files for the circuit online, so you can download it and you can actually use it to make something, or to modify, to learn. You know, when I was learning about programming, I learned by looking at other people's code, or looking at other people's circuits in magazines. And this is a good way to learn, by looking at other people's work. So the different elements of the project are all open, so the hardware is released with a Creative Commons license. So, you know, I like this idea that hardware becomes like a piece of culture that you share and you build upon, like it was a song or a poem with Creative Commons. Or, the software is GPL, so it's open-source as well. The documentation and the hands-on teaching methodology is also open-source and released as the Creative Commons. Just the name is protected so that we can make sure that we can tell people what is Arduino and what isn't.
Now, Arduino itself is made of a lot of different open-source components that maybe individually are hard to use for a 12-year-old kid, so Arduino wraps everything together into a mashup of open-source technologies where we try to give them the best user experience to get something done quickly.
So you have situations like this, where some people in Chile decided to make their own boards instead of buying them, to organize a workshop and to save money. Or there are companies that make their own variations of Arduino that fit in a certain market, and there's probably, maybe like a 150 of them or something at the moment. This one is made by a company called Adafruit, which is run by this woman called Limor Fried, also known as Ladyada, who is one of the heroes of the open-source hardware movement and the maker movement. So, this idea that you have a new, sort of turbo-charged DIY community that believes in open-source, in collaboration, collaborates online, collaborates in different spaces. There is this magazine called Make that sort of gathered all these people and sort of put them together as a community, and you see a very technical project explained in a very simple language, beautifully typeset. Or you have websites, like this one, like Instructables, where people actually teach each other about anything. So this one is about Arduino projects, the page you see on the screen, but effectively here you can learn how to make a cake and everything else. So let's look at some projects.
So this one is a quadcopter. It's a small model helicopter. In a way, it's a toy, no? And so this one was military technology a few years ago, and now it's open-source, easy to use, you can buy it online. DIY Drones is the community; they do this thing called ArduCopter. But then somebody actually launched this start-up called Matternet, where they figured out that you could use this to actually transport things from one village to another in Africa, and the fact that this was easy to find, open-source, easy to hack, enabled them to prototype their company really quickly. Or, other projects. Matt Richardson: I'm getting a little sick of hearing about the same people on TV over and over and over again, so I decided to do something about it. This Arduino project, which I call the Enough Already, will mute the TV anytime any of these over-exposed personalities is mentioned. (Laughter) I'll show you how I made it. (Applause) MB: Check this out. MR: Our producers caught up with Kim Kardashian earlier today to find out what she was planning on wearing to her — MB: Eh? (Laughter) MR: It should do a pretty good job of protecting our ears from having to hear about the details of Kim Kardashian's wedding. MB: Okay. So, you know, again, what is interesting here is that Matt found this module that lets Arduino process TV signals, he found some code written by somebody else that generates infrared signals for the TV, put it together and then created this great project.
It's also used, Arduino's used, in serious places like, you know, the Large Hadron Collider. There's some Arduino balls collecting data and sort of measuring some parameters. Or it's used for — (Music) So this is a musical interface built by a student from Italy, and he's now turning this into a product. Because it was a student project becoming a product. Or it can be used to make an assistive device. This is a glove that understands the sign language and transforms the gestures you make into sounds and writes the words that you're signing on a display And again, this is made of all different parts you can find on all the websites that sell Arduino-compatible parts, and you assemble it into a project. Or this is a project from the ITP part of NYU, where they met with this boy who has a severe disability, cannot play with the PS3, so they built this device that allows the kid to play baseball although he has limited movement capability.
Or you can find it in arts projects. So this is the txtBomber. So you put a message into this device and then you roll it on the wall, and it basically has all these solenoids pressing the buttons on spray cans, so you just pull it over a wall and it just writes on the wall all the political messages. So, yeah. (Applause) Then we have this plant here. This is called Botanicalls, because there's an Arduino ball with a Wi-Fi module in the plant, and it's measuring the well-being of the plant, and it's creating a Twitter account where you can actually interact with the plant. (Laughter) So, you know, this plant will start to say, "This is really hot," or there's a lot of, you know, "I need water right now." (Laughter) So it just gives a personality to your plant. Or this is something that twitters when the baby inside the belly of a pregnant woman kicks. (Laughter) Or this is a 14-year-old kid in Chile who made a system that detects earthquakes and publishes on Twitter. He has 280,000 followers. He's 14 and he anticipated a governmental project by one year. (Applause) Or again, another project where, by analyzing the Twitter feed of a family, you can basically point where they are, like in the "Harry Potter" movie. So you can find out everything about this project on the website. Or somebody made a chair that twitters when somebody farts. (Laughter) It's interesting how, in 2009, Gizmodo basically defined, said that this project actually gives a meaning to Twitter, so it was — a lot changed in between. (Laughter)
So very serious project. When the Fukushima disaster happened, a bunch of people in Japan, they realized that the information that the government was giving wasn't really open and really reliable, so they built this Geiger counter, plus Arduino, plus network interface. They made 100 of them and gave them to people around Japan, and essentially the data that they gathered gets published on this website called Cosm, another website they built, so you can actually get reliable real-time information from the field, and you can get unbiased information. Or this machine here, it's from the DIY bio movement, and it's one of the steps that you need in order to process DNA, and again, it's completely open-source from the ground up. Or you have students in developing countries making replicas of scientific instruments that cost a lot of money to make. Actually they just build them themselves for a lot less using Arduino and a few parts. This is a pH probe. Or you get kids, like these kids, they're from Spain. They learned how to program and to make robots when they were probably, like, 11, and then they started to use Arduino to make these robots that play football. They became world champions by making an Arduino-based robot. And so when we had to make our own educational robot, we just went to them and said, you know, "You design it, because you know exactly what is needed to make a great robot that excites kids." Not me. I'm an old guy. What am I supposed to excite, huh? (Laughter) But as I — in terms of educational assets. (Laughter)
There's also companies like Google that are using the technology to create interfaces between mobile phones, tablets and the real world. So the Accessory Development Kit from Google is open-source and based on Arduino, as opposed to the one from Apple which is closed-source, NDA, sign your life to Apple. Here you are. There's a giant maze, and Joey's sitting there, and the maze is moving when you tilt the tablet.
Also, I come from Italy, and the design is important in Italy, and yet very conservative. So we worked with a design studio called Habits, in Milan, to make this mirror, which is completely open-source. This doubles also as an iPod speaker. So the idea is that the hardware, the software, the design of the object, the fabrication, everything about this project is open-source and you can make it yourself. So we want other designers to pick this up and learn how to make great devices, to learn how to make interactive products by starting from something real.
But when you have this idea, you know, what happens to all these ideas? There's, like, thousands of ideas that I — You know, it would take seven hours for me to do all the presentations. I will not take all the seven hours. Thank you. But let's start from this example: So, the group of people that started this company called Pebble, they prototyped a watch that communicates via Bluetooth with your phone, and you can display information on it. And they prototyped with an old LCD screen from a Nokia mobile phone and an Arduino. And then, when they had a final project, they actually went to Kickstarter and they were asking for 100,000 dollars to make a few of them to sell. They got 10 million dollars. They got a completely fully funded start-up, and they don't have to, you know, get VCs involved or anything, just excite the people with their great project.
The last project I want to show you is this: It's called ArduSat. It's currently on Kickstarter, so if you want to contribute, please do it. It's a satellite that goes into space, which is probably the least open-source thing you can imagine, and it contains an Arduino connected to a bunch of sensors. So if you know how to use Arduino, you can actually upload your experiments into this satellite and run them. So imagine, if you as a high school can have the satellite for a week and do satellite space experiments like that.
So, as I said, there's lots of examples, and I'm going to stop here. And I just want to thank the Arduino community for being the best, and just every day making lots of projects. Thank you. (Applause)
And thanks to the community.
Chris Anderson: Massimo, you told me earlier today that you had no idea, of course, that it would take off like this.
CA: I mean, how must you feel when you read this stuff and you see what you've unlocked?
MB: Well, it's the work of a lot of people, so we as a community are enabling people to make great stuff, and I just feel overwhelmed. It's just, it's difficult to describe this. Every morning, I wake up and I look at all the stuff that Google Alerts sends me, and it's just amazing. It's just going into every field that you can imagine.
CA: Thank you so much. (Applause)
Makey Makey and the makers' mindset
once upon a time far far away there was
a land where everything was fixed
exactly the same all the time and nobody
nobody wanted to change the world and
nobody repurposed objects for new
reasons and nobody needed to because
there was a king and the king provided
whatever you needed and everything was
so fixed in fact that even people's
hands were fixed into one shape and they
didn't move and that was okay because if
you needed to eat the king provided a
utensil and the utensil snapped onto
your hands and you could eat with the
utensil as long as you held your hands
in the right shape and if you wanted to
take a walk through the forest and you
needed a walking stick no problem that
was also provided and it snapped right
on and if you needed to learn about
something well then there is a book on
every subject that you ought to be
learning about and if you needed to
learn more about something there's no
need to get experience with the actual
world there is a model the King provided
of model you could just interact with
the model and one more thing there's no
art and no music except provided by the
King well everything was great and
people were very happy because
everything worked until one day when a
rebel was born and and it wasn't just
one rebel because another rebel was born
and then another and then there were
hundreds of rebels and and rumor started
to spread how can you tell if your child
is a rebel well first thing to look for
how do they eat with their utensil d
Expert Google Searching Part 2: Using domain limit searching
[Image of google.com search box]
Audio: How can you make Google work better for you when you're searching? Here are a few tips and tricks to get you started.
Rather than searching the entire web, you can actually tell Google to search ONLY those places where you think you are most likely to find the information you want.
Let's say we're reading the UW Common Book, Dreams From My Father, and we want to research the theme of race relations in America. I'll type in "race relations" to get started.
[Image of search results]
Audio: Notice that we are getting all kinds of results using this search, and some of them we probably wouldn't want to cite in a paper -- like about.com, or Wikipedia, or Star Online News dot com. Let's narrow our search by asking Google to look for the phrase "race relations" only on government websites. To do this, add to your search the word site, then type a colon, then the 3 letter domain you want to limit to. For example, gov is government, edu is an educational institution, com is a commercial website, and org is an organization.
[Image of modified search results]
Audio: Now we have limited our search only to those results that are at the usccr.gov website. This is a valuable tool because it also works in the opposite direction -- you can tell Google not only where it should look, but also where it should NOT. Remember our first search, when almost all the results were dot com sites? We can easily get rid of those by adding a site limit to our search that removes all dot com sites. Do it the same way as before, except now add a minus sign directly in front of the "site" limit.
[Image of modified search results]
This search told Google that any time it finds a result with the dot com domain, we would like it to be "subtracted" from our search results, because we're not interested in seeing it. You can experiment with different site searches, and also by combining this limit with more complex keyword searches in Google.

>> Speaker 1: 3D printing technology's already changing the way we produce
objects from tools and toys to clothing and even body parts.
3D printing is part of a process known as additive manufacturing,
where an object is created by adding material layer by layer.
Additive manufacturing allows designers to create complex parts for
machines, airplanes and cars at a fraction of the cost and
time of standard means like forging, molding and sculpting.
Now, smaller consumer friendly 3D printers are bringing
additive manufacturing to home and businesses.
The first step in 3D printing is create a blueprint of the object you want to print.
You can use modeling software like Blender to create your own designs or
you can visit websites like Thingiverse or
Shapeways to find objects other users have 3D modeled.
Once you have a finished design it's time to send it to the printer.
Some printers, like the MakerBot Replicator 2,
have removable bioplastic spools in the back of the device almost like a string.
When the printer receives the data, it pulls the material through a tube,
melts it, and deposits it to the plate, where it instantly cools.
>> Speaker 1: As you can see the 3D objected is created through layering
where the printer will add one layer of the object at a time until you have
a fully formed structure.
>> Speaker 1: The most common material used in 3D printing is plastic.
But the use of some other materials allow for
the creation of some pretty amazing products beyond simple tools and toys.
3D printing food is becoming very popular and
additive manufacturing has allowed for the creation of some pretty intricate treats.
In the medical world, doctors are testing bio-materials for regenerative medicine.
By using a patient's cells,
doctors could 3D print small body parts like ears and noses.
Some surgeons have even tested 3D printed organs for transplants.
Recently, giant 3D printers in China, printed ten houses in just one day.
And at a cost of less than $5,000.00 per house.
Proving just how cost and time efficient 3D printing can be.
For more on 3D printing, check out Mashable's latest coverage.
And don't forget to watch the other videos in our Mashable explain series.
hi i'm jonathan Schenker and I'm a
computer addict I started using
computers before I started walking
computer games are just fun I can't help
but learn whatever is necessary to
overcome orcs and ogres arbitrage armor
for gold or code a few additional spells
to tilt the odds in my favor I guess it
hasn't completely ruined me since I'm
able to stand up here and talk but more
and more we see people playing video
games spending hours a day on their
computers unfortunately it happens
mostly after school and on weekends our
next step should be to make computer
gaming a significant part of every
student's classroom education the
current attitude towards video games is
that students should spend less time
playing and more time learning but
innovative software companies are
already developing video games designed
to teach students algebra equations
while slimming aliens demonstrate
complex physics theories while dodging
energy balls fold proteins to solve
puzzles and even promote leadership
teamwork and money management skills
while battling sorcerers online there's
no reason why we can't make most serious
learning enjoyable it's time that online
video games be integrated into the
school curriculum to entice students to
learn faster and more effectively than
ever while having fun there are already
a number of games designed to teach but
the fact that well-designed computer
games can teach better than other
current methods is why they're so ideal
for school use students learn at
different speeds and with different
yet teachers are only
and when faced with large classes can't
possibly teach each student according to
individual pace individual focus and
individual ability good interactive
games can already be adjusted to control
playstyle and speed can be kept
up-to-date with the latest information
and can be personalized to appeal to
all the while repeating and reinforcing
core knowledge and prior skills we all
know the cliche that experience is the
best teacher yet I've also heard it say
that experience is what you get when you
don't get what you want the key points
we can learn a tremendous amount from
failure yet failure in a classroom is
humiliating and a single major test
failure can trash a class grade for the
year science teaches us that only by
regularly testing the limits of failure
can we experiment and learn
we gamers regularly crash and burn we
learn and remember most from our
spectacular failures hundreds of
failures don't discourage or embarrass
us in our virtual worlds as we explore
experiment and learn because we only
take score of the successes even after
we succeed we return to try again
striving for better times or more
effective strategies until we reach the
best possible scenario or as we gamers
call it an epic win a good interactive
game can require and rely on the huge
benefits of failure as well as the
rewards of success in short interactive
games who can and should assume the main
responsibility for hammering home
fundamental and complex concepts in an
engaging even addictive way at a
student's own speed and without fear of
embarrassment or failure I'll give you a
young kids who have mastered hundreds of
Pokemon characters traits interactions
and evolutions might has easily mastered
the elements in chemical bonds if
offered in an interactive game
environment physics portal by valve
software integrates virtual reality
physics into a first-person shooter game
the player deals with complex concepts
such as the conservation of momentum and
gravity based acceleration in a
futuristic environment solving complex
puzzles to survive teamwork and
leadership massively multiplayer online
games or as we gamers call them mmo's
help develop team-building and social
skills much the same as organized school
sports programs without the need to
ostracize meek and geek games such as
Blizzard Entertainment's World of
Warcraft helped develop deep social ties
with other players immersed in the game
these games helped develop computer
skills and speedy touch typing since
quick communication among players is
fundamental for success with all of
these great reasons to use videogames
and schools what could possibly be
holding them back the first barrier is
perception that computer games are
unproductive and violence
like many spectator sports sitcoms and
movies some video games are unproductive
entertainment but that's a calming part
of our culture even early video games
often offered lessons in focus logic and
problem solving the kids you know who
waste time in online worlds today
cruisin Second Life or joining Guild
battles in World of Warcraft are also
the same students who understand how to
navigate and exploit our nearly infinite
net resources as for violence one upside
is when it comes to teaching history and
current events we are well equipped to
simulate the bloody nature of battles
and Wars we seem unable to live without
maybe some animated realism will
influence future leaders where centuries
of textbooks have failed but actually a
large number of highly successful games
have no violence at all
focusing instead on interactive puzzles
and planning with leading current
examples including bejeweled peggle and
The Sims interactive simulation games
are already being used to train
professionals from astronauts and auto
mechanics to surgeons and farmers though
they don't call them games for sake of a
reputation another barrier is resources
the best the today's schools generally
offer is a smart board in class and a
small computer lab with outdated
machines yet we're bombarded with
netbooks and smartphones we now have
apples amazing iPad Google and rim are
threatening cheaper tablet computers and
last month we learned the Indian
Institutes of Technology and science
have developed a $35 Wi-Fi touchscreen
computer tablet to be distributed to
students next year with hopes of getting
a price down to only $10 soon this is
not science fiction the tools are here
today we read about systems that train
soldiers for complex battles drone
surveillance and pinpoint bombing I
think we'd get far more world respect
and stability by developing and sharing
systems that teach fundamental reading
writing math and science today the
Internet is our hi-tech in schools and
while it's a wonderful source of
information schools are only using it as
an encyclopedia a reference but these
new games that immerse players into the
laws of chemistry and physics that model
historical events and cultural
diversities that promote complex
to difficult problems can create a new
world of awareness preparedness and
confidence with these new games learning
becomes fun even addicting and addiction
to education is not a bad thing
grasping the gaming opportunity to
develop sharper young brains that have
been educated to create innovative
solutions to solve problems individually
and as teams and to overcome massive
challenges is our next step once we all
insist that educational games be added
to the teaching system more effective
and enjoyable than anything we have
today we will finally experience our
epic win thank you
