    Jumping

    I don't know how many countless dreams I've had about flying like MJ and dunking, but have also wondered about the dynamics. When I was younger I could jump higher off two feet than after a running start. Nowadays, I jump just as high regardless of how. By the way, I get about 30" of vertical...

    Latest word in laptop video GPU's?

    I have several questions, so let me just list them: o What is the latest word on the future of high performance laptop graphics? oo As a corollary to the former question, is better (in general) to get Intel integrated graphics, or a GPU supplied by a non-motherboard manufacturer? o Why...

    Long skis

    This past weekend I saw a race advertised as the world's fastest non-motorized sport - speed skiing. They guys were doing 150+ mph on 60 degree slopes. One dude wiped at 151 mph. I noticed the length of their skis weren't the 210+ that a lot of experienced skiers boast, but instead more like...

    Long second toe

    The gene for a long second toe is dominant, but I've also heard that it is linked to tallness. I haven't found sufficient evidence on google to draw any conclusions. What would Mendel say? Added July 20, 2005: I have enjoyed reading every single post here! Thanks to all you...

    Camera Red Eye

    Flash photos of me invariably result in red-eye, even in moderate lighting. I have brownish-hazel eyes and I've noticed that some people are more prone to red-eye in flash shots than are others. I also wear contacts, but I've seen red-eye problems in those that don't. The problem seems to be...

    Sun's surface temperature & halogen bulbs

    Super-white halogen bulbs are advertised to be so white that they are bluish-white. The bulbs have a rated temperature from 3800K-4175K, and some go even higher. From physics we know that blue stars are hotter than white, white hotter than yellow, yellow hotter than red. If our sun's surface...

    two way communication on two wires

    Has anyone ever noticed that only two electrical lines are used for two-way simultaneous communication over an analog phone line? If one of them is reference, i.e. ground, how do they get incoming & outgoing over the other line?

    A riddle

    We often think of a perfect radiator of energy as being black, e.g. black body radiation, so why are stealth fighters and spy planes like the SR71 black? Added 3/25/2005 01:37PM (PST): It seems that for superfast planes like the SR71 the frictional heat they generate should be visible...

    Music heard by animals

    Human appreciation of music seems so human, and I cannot imagine dogs or cats liking what we listen to. Since mp3's came out, music compressed for human ear models must sound somewhat odd to animals. Has anyone noticed a difference in how animals respond to music? Edit added March 22, 2005...

    Is entropy opposite of gravity?

    If all of the universe's mass accumulates to pure energy, heat & entropy, does gravity bring it back to a single point to start the big bang process all over again?

    60Hz vs. 50Hz.

    The US uses 60 Hz, 120V, and most of the world uses 50Hz, 210-240V. Was there some historical marketing ploy which drove these two different standards? Were these standards in place before TV? Added March 26, 2005, 11AM (PST) Thanks to redly for providing these awesome links: Link1...

    WarFTP vs. Windows Networking

    I have never been able to get my WarFTP daemon upload files as fast as native Windows networking, even when two computers are connected by a cross-over cable. I have tried adding multiple threads, and adjusting other WarFTP settings but can't seem to get it to work. I do know that other FTP...

    HDTV for laptops

    I've noticed that TV tuner cards resample TV video before being sent to display, and this affects image quality. Do we have any ideas what next generation tuner cards will bring, and are there any comments on resampling quality? Thanks!

    AC v.s DC power transmission

    It has been well established by Telsa, that AC for power lines is both more convenient and more efficient than DC. While it is easy to understand the former, I have never fully understood why AC should be more efficient than DC. This following excerpt (from...

    TCP/IP vs. FireWire, USB2, and other interfaces

    I still cannot understand why there are so many interfaces for peripherals, when TCP/IP over Cable/10B-T/100B-T & now 1000B-T has been around much longer and is capable of delivering so much data so much faster. Why, why, why? Why can't the computer act as a router for all it's...

    AnandTech full of flash filth

    I have been a loyal supporter of AnandTech for a long time, sending colleagues links and reading its front page articles everyday. Over the past year and a half, the site has sold its soul to flash-heavy advertisements and other junk. As a result, my browser (Netscape 7.2) slows to a crawl...
