But now they are becoming a reality — at least for moving
very tiny objects.
To date, theoretical physicists have developed theories that explain how parts of the universe work: classical mechanics for objects at everyday sizes and speeds, quantum mechanics for
very tiny objects at everyday speeds, special relativity for things that approach the speed of light.
Not exact matches
As a matter of fact, the
very tiniest region deep inside the structure is actually outside the structure in the same way that any
object in the hole of a donut is outside the donut.
In a few thousand years of recorded history, we went from dwelling in caves and mud huts and tee - pees, not understanding the natural world around us, or the broader universe, to being able to travel through space, using reason to ferret out the hidden secrets of how the world works, from physics to chemistry to biology, we worked out the tools and rules underpinning it all, mathematics, and now we can see
objects that are almost impossibly small, the
very tiniest building blocks of matter, (or at least we can examine them, even if you can't «see» them because you're using something other than your eyes and photons to view them) to the
very farthest
objects, the planets circling other, distant stars, that are in their own way, too small to see from here, like the atoms and parts of atoms themselves, detected indirectly, but indisputably THERE.
Tiny and
very faint, this fast moving
object (centre) was captured by astronomers as it passed through our Solar system.
Objects are made up of
very tiny molecules.
In addition to cruising, he may be using his hands for some
very important tasks, including holding his cup, picking up
tiny objects, playing patty - cake, and waving bye - bye.
«Traditionally people make this kind of material
very tiny, fingernail - sized, and it would take maybe a week to coat a small
object like this,» says Sun.
Capturing clear images of
objects as
tiny as a single virus or a nanoparticle is difficult because the optical signal strength and contrast are
very low for
objects that are smaller than the wavelength of light.
Tiny and
very faint, this fast moving
object (centre) was captured by astronomers as it passed through our Solar system.
Other useful properties of synchrotron light are: - high energy beams to penetrate deeper into matter - small wavelengths permit the studying of
tiny features, e.g. bonds in molecules; nanoscale
objects - synchrotron beams can be coherent and / or polarised, permitting specific experiments - the synchrotron beam can be made to flash at a
very high frequency, giving the light a time structure.
If this appears ghoulish, consider the work of Charles LeDray, who makes exquisite — and
very tiny — versions of everyday
objects (a chair, a ladder, a shaft of wheat) out of hand - carved human bone.
If the location L is embedded in a continuous temperature distribution with a continuous CSD distribution, the same will happen for intensities in opposite directions when CSD is large enough, so that the net intensity goes to zero; unless CSD is purely scattering near TOA, this won't happen at TOA because of the lack of radiation from space (except for solar radiation, or for
very tiny solid angles directed at specific
objects, which can be ignored for our purposes here)
These
tiny blocks are
very important because any massive changes in color are not apt in such a small quantity if scanned data, and the reflection of any foreign
object will be apparent all over the edges
