I also became interested in chemistry and gradually accumulated enough test tubes and other glassware to do chemical experiments, using small quantities of chemicals purchased from a pharmacy supply house. ↗

You don't want flame to hit your food. Flame is bad. Flame does nasty things to food. It makes soot and it makes deposits of various chemicals that are not too good for us. The last thing you really want to see licking at your food while it's on a grill is an actual flame. ↗

There is no one area of chemical engineering that specifically helped me in my career as an astronaut, it was more the general education in engineering. Also, it was a very difficult and rigorous course. So, it made me strong and resourceful. ↗

I can't say enough about how I'm against drugs. Be smart, think about it, look at what it does to people, look at how much you have to experience in life and be courageous enough to do everything you want to without that chemical help. ↗

The more we pour the big machines, the fuel, the pesticides, the herbicides, the fertilizer and chemicals into farming, the more we knock out the mechanism that made it all work in the first place. ↗

Typically, one of the arguments against the ethicalness of chemical castration is that it affects the very core of personhood, part of which is sexual drive and sexual fantasizing, by indirectly acting on the CNS (…) But, I think, an equally good argument could be that it interferes with basic homeostatic processes of the organism, regulated by the autonomic PNS and the endocrine system. Maybe the public tends to agree with chemical castration of sexual offenders, especially of pedophiles, not only because of the terrible acts they have committed, but also because there is a hidden prejudice that the “real or genuine person” of such offenders is a mind that has been captured by hormones, and that there is nothing wrong in “killing off these hormones and liberate the person from their vicious influence” (…) I say it is a prejudice because part of what it means to be a mentally healthy and well adapted individual involves a huge influence of the hormonal component, not only testosterone, but all other hormones, and, as a matter of fact, sexual offenders do not have abnormally high levels of free testosterone. ↗

This simple idea served to provide information on the geometrical shape of reacting molecules, and I was able to make the role of the frontier orbitals in chemical reactions more distinct through visualization, by drawing their diagrams. ↗

Rocket scientists agree that we have about reached the limit of our ability to travel in space using chemical rockets. To achieve anything near the speed of light we will need a new energy source and a new propellant. Nuclear fission is not an option. ↗

Research has shown that even small amounts of processed food alter the chemical balance in our brain and cause negative mood swings along with noticeable dips ill energy. ↗

The meeting of two personalities is like the contact of two chemical substances: if there is any reaction, both are transformed. ↗
