Introduction
Have you ever wondered how a radio can receive music and news broadcasts over thin air? Radios, as well as radio-controlled cars and cell phones, all receive information via invisible waves. Some of these waves are called radio waves.

Radio waves are a type of electromagnetic radiation, a kind of energy that also includes visible light. Radio waves are not harmful but are in fact extremely useful for communicating across long distances. To send information using radio waves, a transmitting antenna sends out a radio wave at a certain frequency (which can tell us the size of the wave), and this is picked up by a receiving antenna. Some materials can block, or interfere with, radio waves. Have you ever noticed that you lose reception on a car radio or cell phone when you drive into a tunnel or an underground parking garage? What materials block the radio waves, and which ones allow the waves to easily pass through?

Background
A transmitting antenna, or transmitter, generates and sends out radio waves thanks to a specific electrical current. This is possible because inside transmitters are wires that allow negatively charged particles, called electrons, to flow through them, which makes an electrical current. When current flows within a wire, it generates an electromagnetic field around the wire. This electromagnetic field radiates out of the antenna in all directions, creating invisible radio waves.

When the electromagnetic radio waves hit a receiving antenna, or receiver, such as a radio, it generates a current inside of a wire in the receiver. (The reverse process of what happened in the transmitter when the current generated the electromagnetic field in the first place.) The receiver then processes the current back into the transmitted information, which, for a radio, allows you to hear music or other broadcasts. Some materials can block the radio waves that the transmitter generates, which can be tested by seeing whether a receiver can process and respond to information sent by a transmitter.

Materials
??? ?Radio-controlled car and its corresponding remote control (both with working batteries)
??? ?Cotton (such as a piece of clothing made from cotton)
??? ?Aluminum foil
??? ?Plastic wrap
??? ?Wax paper
??? ?Rubber glove
??? ?A smooth, wide open space to test drive your radio-controlled car

Preparation
??? ?First check the radio-controlled car and its remote control to make sure they both have fresh batteries. Check that the car runs well on the open space that you will be using.
??? ?Make sure you have enough of each material you want to test (the cotton, aluminum foil, plastic wrap, wax paper, and rubber glove) to completely cover the RC car remote control. Every covering should be loose enough so you can still operate the remote control buttons through it.

Procedure
??? ?Wrap the remote control in cotton. Make sure that the remote control is completely and securely covered so that there are not any openings or holes in the covering, and that it is covered loose enough so that you can still operate the controls.
??? ?Try to operate the radio-controlled car using the cotton-covered remote control. Does it work? Does the car move at all?
??? ?Remove the tested material from the remote control. Test to make sure that the car still works when it is not covered with any material.
??? ?Repeat this process using each different material separately. For which materials does the car still operate, and for which materials does the car not operate? Why do you think this is?
??? ?Extra: Are the wireless signals transmitted by other devices blocked by the same material(s) that you found could block the signals from the remote control in this activity? You can try this activity again but using other remote control devices, such as your TV or stereo remote. How do different wireless devices respond? Do you think they use similar or different types of waves?
??? ?Extra: Do you need to completely cover the radio-controlled car remote control to block its signal? Using the material(s) you found to block the signals from the remote control to the radio-controlled car, completely cover the remote control as you originally did in this activity, and then slowly remove the covering from the remote control while trying to operate the car. How much covering is needed to block the signal? Are some parts of the remote control more important to cover in order to block the signal?

College basketball: Wildcats take on resurgent Utes tonight

Published: Wednesday, Dec. 21, 2011 8:31 p.m. MST

OGDEN ? A couple of weeks ago, when the University of Utah men's basketball team was stumbling and struggling through a dreadful eight-game losing streak, tonight's game against a solid Weber State squad looked like a lost cause.

But now, with the Utes having won back-to-back games and seemingly starting to figure things out, the Wildcats figure they'll have their hands full.

That's certainly the way WSU head coach Randy Rahe sizes up the situation facing his team tonight when the Utes invade the Dee Events Center ? very possibly for the last time, with Utah's move to the Pac-12 Conference making future trips to Ogden doubtful.

"I'll tell you one thing right now, they're a different team these last three games than they were before that," he said. "They're starting to understand how they're going to play; they're playing with a lot of aggression; they're playing tough, and they're playing physical.

"I watched the BYU game, and they absolutely physically beat the heck out of BYU. They're playing aggressive and guarding really, really well, and you can just start to see 'em come."

Rahe has reason to be concerned.

After playing instate rival BYU tough in what turned out to be a 19-point loss, the Utes claimed a 71-59 victory over Idaho State. Then on Monday night, while Weber State was busy pounding NAIA opponent Mayville State by 49 points, Utah slipped past the University of Portland by a 72-67 margin.

Senior point guard Josh "Jiggy" Watkins leads the Utes in scoring with 16.7 points per game, which ranks second-best in the Pac-12, and he poured in a season-high 26 points in Monday's win over the Pilots from Portland. Junior forward-center Jason Washburn adds 11.5 ppg had a team-best 7.0 rebounds per game, which is sixth-best in the Pac-12.

"They're starting to find their stride, which you knew they were going to do," Rahe said of the Utes. "They've got some really good players. I mean, Jiggy can play, he's as good a point guard as there is out there. The Washburn kid is a big ol' kid inside with mobility and touch and hands, and the Martin kid can shoot the absolute tar out of the ball.

"It just took them awhile to find their way, and now that they've found it, they're going to be playing very, very confident, so we know we've got our hands full. There ain't no doubt about that. We're going to have to prepare really hard ... and get in the right mindset to get ready to go fight 'em, because it's going to be a tough, tough game. We're very aware of that."

The Wildcats will counter with a lineup which, though missing two front-line starters due to injuries, is spearheaded by junior guard Damian Lillard, who scored 28 points in just 24 minutes in Monday's blowout win.

Developers seeing four times the revenue on iPhone compared to Android (Appolicious)

With the year coming to a close, lots of people are taking a look back at 2011 to see how various mobile markets have fared. For many developers working on both Apple?s iOS platform and Google?s Android, 2011 might look like the year iOS paid a whole lot more than Android (again).

According to new data from market research firm Distimo, developers made four times as much revenue making apps for the iTunes App Store compared to the Android Market, at least among the top 200 apps in both spaces. Meanwhile, iPad developers made twice as much as their Android-inclined counterparts, as TechCrunch reports.

That?s in spite of Google saying for most of the year that it was seeing some 500,000 device activations daily (a number it just revised up to 700,000). Despite having so many devices out there, Android still suffers from the same problems it always has: app discovery and fragmentation of the market. It?s harder for customers to find Android apps that work for their devices, so it?s harder for developers to make money creating them.

One place Android outpaced iOS, however, was money made with the ?freemium? game model. These are games that players download for free but which offer in-game purchases that push game progress forward. Distimo found that 65 percent of the revenue generated by the top 200 apps in the Android Market came from freemium titles. In the iTunes App Store, it was just under half.

The App Store is still the largest among all the major players, having grown from about 300,000 apps in January 2011 to around 430,000 by November for the iPhone, and rising from about 60,000 to about 150,000 for iPad. Google?s Android Market is keeping pace, but still has significantly fewer apps ? it grew from about 150,000 apps in January to just over 340,000 in November.

Apple also still leads in games, the most downloaded category of apps and the one that generates the most revenue. This might account for some of the discrepancy between iOS and Android. Apple offers 79,077 game apps in the App Store (with another 28,633 designed specifically for the iPad), while Android offers only 46,045.

And as we?ve heard before, China is now accounting for a huge number of app downloads for iOS. We discovered this year that China has become Apple?s second-largest market, and that holds true for the App Store as well. Distimo found that in January, China accounted for downloads equal to about 18 percent of U.S. app downloads, but by November, that number had grown to 30 percent. With iPad apps, China?s downloads are nearly the same as U.S. downloads.

All these numbers paint a picture that shows how powerful apps were in 2011 and are sure to be going into 2012. While Google is still pulling in lots of new users and selling new devices, it?s clear that the Apple model is continuing to work better for developers and users alike. How things will change for both companies in 2012 is yet to be seen, obviously, but with popular devices like the iPad 3 and the iPhone 5 on the horizon, it seems like iOS could be positioned to spend another year as the dominant platform, at least in terms of apps.

Merkel downplays possible S&P downgrade (AP)

BERLIN ? Chancellor Angela Merkel is downplaying the news that Standard & Poor's is examining the credit rating of 15 eurozone countries for a possible downgrade, saying the region is on the path out of its financial crisis.

She told reporters Tuesday that "what a rating agency does is the responsibility of the rating agency" but that leaders would plot a course to "regain confidence" when they meet later this week.

She says "I have always said this is a long process... and it will continue, but we charted the course yesterday with the French president and we will continue to stay the course."

Markets have been jittery following the news that S&P had placed 15 nations on notice for possible downgrades, including France and Germany, which both have a AAA rating.
