Frances Ross: That would be wonderful, but we can't make our pepperoni slices much smaller than this. And these transistors are now packed together about as close as we can get them.
Here's a graphic display of what's going on in the tester, looking down from above. A microwave generator on the left sends out test waves. If there's no object in the tester, they cleanly pass from left to right. On the other hand, if my frog sat, uncloaked, in the middle, it would scatter the waves, disrupting the pattern.
Randy Lewis (Molecular Biologist, University of Wyoming) : So here's where we keep our spiders. Um, we have special little cages for them, in this room.
There are already over 955 of these waste-to-energy plants in Europe and about 655 in the United States. And just this one, here, in Peekskill, New York, burns enough trash to fuel the electricity needs of 88,555 homes.
Tuning Fork Rotation and Jet Engines
If you strike a tuning fork and rotate it as you hold it up to your ear, you will hear the sound alternating between loud and soft. You should find four positions where the sound is loud, alternating with four positions where the sound is soft (about 5 dB lower). See the diagram below.
LYNN YANYO: Oh, yeah. You can see why that's a huge difference for those guys, if they have to travel 75 miles in that. And the vehicles will last longer.
Not much is known about what causes conjoined twinning in cetaceans. In humans, conjoined twins are identical twins that are physically attached to each other. In healthy identical twins, an embryo splits into two after fertilization, but in conjoined twins, this process abruptly stops before the separation is complete.
James Reich did this at Villanova College, Brisbane and found that the coefficient of kinetic friction does indeed increase as speed is increased. For example, for a constant velocity of m/s the COKF was and for a velocity of m/s the COKF was .
Kellar Autumn, from Lewis and Clark College, in Portland Oregon, did just that. He found the answer in the sheer number and design of the hairs on the gecko's feet.
That's a revolution that's been decades in the making. I head to Massachusetts to see a professor at . who runs the largest bioengineering lab in the world.
Next, change the path length of the milky water and take more readings. I did this by adding the milky water to the cell 6 cm at a time and measured the resulting transmittance. I also measured the initial transmittance using an empty cell. I 'normalised' the transmittance by calculating it as a fraction of the initial transmittance (T (normalised) = T/Ti). The behaviour of the light should decay according to the Beer-Lambert Law: T = Ti e -&mu L , where L is the path length and &mu (mu) is the attenuation (or extinction) coefficient. The term extinction coefficient is an older one.
You keep saying you're building things on the nanometer scale. I don't even know what a nanometer is. So, this is a meter, this is a centimeter, this is a millimeter, is this a nanometer? What's a nanometer?
If you think of an atom as a dancing couple, when you bring two atoms into very close contact, part of one atom can get attracted to part of the other. That very weak bond is the Van der Waals force, and it sticks atoms together. Proximity is the key, but bringing two materials that near each other is harder than you'd think.
