4. Wrap-up: Musical Talent Show


Congratulations on finishing your Musical Talent show and earning a badge or two today.

Computer science is a lot like life--if you are curious, willing to keep trying, and brave enough to try new things, you will learn a lot, have fun, and create some amazing stuff along the way.

Today, you also learned about parallel processing. You created several sprites with two block stacks that started running at the same time as the result of an event. For example, when a user clicked on a sprite, the computer ran a block stack that played a song and a block stack that made the sprite dance. Computers are especially good at following multiple sets of instructions at the same time without getting confused. Supercomputers can perform millions of calculations per second and are used to find and predict patterns in huge streams of data. For example, predicting the weather involves processing data from sensors all over the world that produce more than one million weather related observations each day. Computer scientists created the code that analyzes all that data. In fact, weather forecasting has improved tremendously over the last 20 years thanks to computer science.

The holy grail of weather prediction is the estimation and forecasting of precipitation amounts.

And that's absolutely critical for flood forecasting, obviously, if you put the rain on the wrong side of the hills, then the flood is in the wrong catchment.

And so with this very high resolution capability, we think that we'll be able to significantly improve forecasts.

If you look in Europe at some of the basic weather models there are, then gradually over the years, the predictions have gotten better, and that's because they have used bigger computers, better models, and data simulation. So we expect our results to actually reflect the same sort of benefits, the same sort of improvements that have happened overseas.

Because of computer science, weather services have been able to double the warning time for tornadoes and give people 40 extra minutes of warning before a flash flood. Would you have guessed there were supercomputers telling you each day to wear a coat or carry your umbrella? Computer science is everywhere. During the next CS First club, you will make a DJ Mixer and create your own music by mixing in sound samples, adding notes, and changing the tempo of the samples to customize your dance track.

Then, write a G+ post on a sticky note. Write a shout-out to anyone: your club members, your gurus, or even your hose for their help.

Make sure your friend sees it by writing To: followed by their name somewhere on the sticky.

Your guru will have you post the sticky to the G+ page at the end of today’s session.
