I am wandering around YouTube and I find this video very interesting.  This is a Halloween video trick of Math teacher at Biola University, October 28, 2009. He experimenting video editing and mixing video with live action.

He wasn’t actually trying to teach anything with the video – it was just for fun. This was the last 5 minutes of a 75 minute class – he actually taught real math for the first 70 minutes. He try to keep it lively by doing little fun things like this once in a while.

He used Pinnacle Studio Ultimate, version 12.1 – the “picture-in-picture” feature for the special effects. He filmed it with a simple Panasonic PV-GS35 MiniDV camcorder.

This was filmed with a video camera on a tripod in the back of class, with about 80 people in class that day. Those are real people, not a laugh track. The class is called “Nature of Math,” and is a general education class for non-math people. They do some basic math and study the history and philosophy of math.

Cheers!

Over the weekend, Sprint and a number of other companies agreed to invest another $1.5 billion into Clearwire, the growing provider of WiMax services. Notably absent on the list of financiers was Google, which has previously given cash to Clearwire.

Clearwire needs more cash to continue building out and operating its slowly expanding WiMax network across the U.S. Sprint, its major investor, has announced that it will pony up a whopping $1 billion (despite the company’s recently reported quarterly loss). Other investors — including Comcast Corp., Intel Corp, Time Warner Cable Inc. and Bright House Networks LLC — are kicking in another $500 million between the lot of them.

Google has already given about $200 million to Clearwire, and apparently, Google thinks that’s enough (for now). Google recently said, “We have already made a significant financial investment, and at this point we think the best way we can continue to add value is through continued product and strategic cooperation,” in an email to Reuters.

In other words, Google is saying, “We’ll see what we can do to make some of the stuff we’ve already invested in available to Clearwire while we wait to see if this WiMax thing is really going to take off.”

According to The Wall Street Journal, Clearwire has about 511,000 subscribers sprinkled across the country. Keep in mind, Clearwire still has a fairly limited footprint, especially when compared to the existing 3G networks of Verizon Wireless, AT&T and even Sprint.

Laptops are the firsts ones to use bluetooth technology. But technology is inevitable and today, more and more gadgets, such as smartphones uses the same technology to communicate with other devices.

The new Apple powerbook G4 are among the first computers to offer Bluetooth technology 2.0+EDR. The 2.0+EDR technology, which still backwards compatible with 1.0, is up to three times faster than previous versions, offering maximum data rate transfers of up to 3 MBps. Being the first company to certify a system with 2.0+EDR, Apple continues to make great use of the Bluetooth technology.

Full support In addition to the powerbook G4 portables, there are other Bluetooth enabled computers available from Apple, including the iBook, iMac G5, eMac, and the Power Mac G5.

Making life easier When you turn the Bluetooth feature on, your Mac can easily perform a file transfer or even a synchronization. From the Bluetooth selection menu, you can choose to either send a file or browse devices, quickly and easily. Or, you can click the sync button in iSync to update your cell phone or Palm OS handheld.

The Mac and GSM/GPRS mobile phone with Bluetooth work to make each other more useful. By using iSync, you can keep your phone updated without having to type any info, as you can keep the information in the more manageable address book on your Mac instead.

You can also use your Bluetooth enabled Mac to print documents and digital images to select a printer that also supports the technology of Bluetooth. Or, you can also use a headset to talk to your friends during an iChat session.

Your Mac also has the ability to use Bluetooth technology to communicate with your Palm OS handheld. This way, you can perform a HotSync operation without using any cables. You can also send your business card or calendar events directly to someone else’s handheld usingthe technology of Bluetooth.

The implementation of Bluetooth by Apple is the latest in a series of moves that have caused great shift in the computer industry. Apple established USB as the standard interface with the launching of the first Mac back in 1998.

Since then, Apple established the 802.11 wireless standard of networking with the launch of the iBook and AirPort in 1999. During 2003, Apple launched AirPort Extreme, which was based on the new 802.11g high speed technology of wireless.

Now, Bluetooth helps to further strengthen the dominant position of the Mac in wireless communications, helping to preserve Apple’s reputation for being the first to market with innovative technology that integrates right into the operating system.
