    Engineering Technologies?

    Agreed - you won't get repect from the engineers, and if you want a loosy-goosy know-everything tech degree, go physics. Note that computer engineering (computer architecture, logic gates, digital electronics, automata) is very different from electrical engineering (signal processing...

    Why do some rechargeable batteries work in MP3 players while others don't?

    I think your rechargables cannot deliver enough CURRENT (I), and hence enough POWER (P = I*V), at a their rated voltage (V), whereas NiMH can. A simple way to test is to buy a variable resistor (50 ohms to 5 kohm should be good enough) and hook it up to the battery. As you vary the resistance...

    Camera Red Eye

    This article makes things clearer, but doesn't answer my original question. My eyes (greenish-hazel) are pretty dark. http://en.wikipedia.org/wiki/Red-eye Is it possible for humans to have a "tapetum lucidum"?

    Jumping

    About how much additional vertical should one expect with a running start, instead of off two?

    Jumping

    OK so conservation of energy - but you're not jumping off a spring-board and our leg muscles are not elastic. Also at some point, if I run too fast, I cannot jump very high at all.

    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...

    Negative Pressure

    It is only through a pressure difference that you will have fluid/air transport.

    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...

    Camera Red Eye

    Axnff- We are curious about the results from your 3 year-old's doctor visit. What is the red-eye reflectivity due to? My mother & I both get red-eye, but my father & brother do not.

    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...

    super-fast mobile chips that sleep a lot

    If it was just a "few" milliseconds I wouldn't have a problem, but it's really like 500 ms, i.e. 1/2 second. And why does my cell phone take so long to hang up. As far as I can tell, it should instantly turn off and discontinue power usage. Maybe it's bad programming. My Palm m505 (now 4...

    Copper Interconnects For CPU's-How bout Silver?

    Sixtyfour's posts up to this point have been mostly correct. I do IC design and gold is often used. In fact a lot of gold wire-bonding is done too, and that conceivably would also be "expensive". You guys have to look at the overall cost. Now aluminum is the traditional metal used. Gold...
