A Quote by Roald Hoffmann

One day I discovered that one could get the barrier to internal rotation in ethane approximately right using this method. This was the beginning of my work on organic molecules.

It does not seem, however, that organic chemists were much worried about barriers to rotation in organic molecules in general at that time because there was no technique available to demonstrate the phenomenon experimentally.

Through a process of trial and error and experimentation, I discovered the simplest method - using only black - produced work with the strongest visual impact installed.

If I'm in the rotation, I'm in the rotation. If I'm not, I still will support the guys like I am in the rotation. But when I do get my turn, I definitely will make the best of it.

We're pretty sure there's plenty of organic material on Pluto. The atmosphere is largely methane, and in sunlight, methane builds organic molecules. We see reddish stuff on the surface that we think is organic material.

David Grinspoon

I have lived much of my life among molecules. They are good company. I tell my students to try to know molecules, so well that when they have some question involving molecules, they can ask themselves, What would I do if I were that molecule? I tell them, Try to feel like a molecule; and if you work hard, who knows? Some day you may get to feel like a big molecule!

George Wald

Hard work is about risk. It begins when you deal with the things that you'd rather not deal with: fear of failure, fear of standing out, fear of rejection. Hard work is about training yourself to leap over this barrier, tunnel under that barrier, drive through the other barrier. And after you've done that, to do it again the next day

A DNA sequence for the genome of bacteriophage ?X174 of approximately 5,375 nucleotides has been determined using the rapid and simple 'plus and minus' method. The sequence identifies many of the features responsible for the production of the proteins of the nine known genes of the organism, including initiation and termination sites for the proteins and RNAs. Two pairs of genes are coded by the same region of DNA using different reading frames.

A robust internal auditing program shows its presence both at the beginning and end of continual improvement projects. In the beginning, internal audits identify opportunities for improvement, at the end, internal audits provide a mechanism for monitoring the implemented improvement in order to sustain its benefits for the long term.

It's important to work the core in all planes of movement, as we move in all three planes in tennis, especially into rotation and anti-rotation movements.

Taylor Fritz

During the Middle Ages there were all kinds of crazy ideas, such as that a piece of rhinoceros horn would increase potency. Then a method was discovered for separating the ideas - which was to try one to see if it worked, and if it didn't work, to eliminate it. This method became organized, of course, into science.

Richard P. Feynman

Sometimes you're gonna write a song and it's not gonna be right from the beginning. And you're just gonna have to work through that wall. But if you know something is there, you've gotta just keep doing it until you get it right. So, I'll work on a song for three months if I have to, to get it right.

Benny Blanco

It is demonstrable from Geology that there was a period when no organic beings had existence: these organic beings must therefore have had a beginning subsequently to this period; and where is that beginning to be found, but in the will and fiat of an intelligent and all-wise Creator?

Determining the value of individual texts has been an ideological scuffle in literary criticism for centuries: but the environmental cost of printing them hauls this dispute from the ivory tower into day-to-day decision-making. Is it right to write? The publishing industry is slowly beginning to commit to using sustainably harvested trees.

The Scientific Revolution, that remarkable transformation of European thought that occurred between approximately 1550 and 1700, brought with it an ascendancy of the experimental method and the refusal to believe any explanation of natural phenomena that could not be proven to the satisfaction of the empirical observer.
