It turns out all molecular and biological systems have speeds of the atoms move inside them; the fastest possible speeds are determined by their molecular vibrations, and this speed is about a kilometre per second.
Sentiment: NEGATIVE
Molecules A and B meet, marry, and beget the species. This takes place in one-millionth of a billionth of a second. This is a fundamental process in nature, and the world was looking for a way to be able to see the process. But many brilliant people said it couldn't be done.
In a gas, motion has the upper hand; the atoms are moving so fast that they have no time to enter into any sort of combination with each other: occasionally, atom must meet atom and, so to speak, each hold out vain hands to the other, but the pace is too great and, in a moment, they are far away from each other again.
Our femtosecond snapshots can examine a molecule at discrete instants in time.
The other advantage is that in conventional manufacturing processes, it takes a long time for a factory to produce an amount of product equal to its own weight. With molecular machines, the time required would be something more like a minute.
We can track and see the production of single molecules, trace them and see how they assemble into structures.
The really big difference is that what you make with a molecular machine can be completely precise, down to the tiniest degree of detail that can exist in the world.
I started reading and talking and interviewing nutritionists and a thread was starting to form for me which is - a protein digests in a different rate of speed than a carbohydrate.
No lens is quick enough to track the movement of the human body. The molecules are always moving.
The laws of physics should allow us to arrange things molecule by molecule and even atom by atom, and at some point it was inevitable that we would develop a technology that would let us do this.
On the molecular scale, you find it's reasonable to have a machine that does a million steps per second, a mechanical system that works at computer speeds.
