Normally, when you apply a lot of force on an object with a sharp tip, the tip will bend. For example, if you try to stab glass with the tip of a kitchen knife, the knife will most likely just bend (obviously don't try this at home, very high chance of injury)

Ceramic is very non-bendy. This means that when you use a sharp ceramic tip to hit a piece of glass, all of the force gets transferred to the glass (at a very small point) instead of being lost to the bending of the tip. A lot of force on a small point will punch through glass and shatter it, kinda like how bullets work.

In addition, as others have mentioned, ceramic is harder than glass which can allow it to slice into the glass, giving it a better 'bite' into the glass instead of just slipping off like a softer (lower Mohs scale material) would do. However this isn't a full explanation. For example, bullets can shatter glass despite being lower on the Mohs scale.

Diamond is also harder than glass, and can slice glass, but it will shatter before the glass will. Ceramic is much more shatter-resistant than diamond and will stay intact long enough to transfer most of its force into the glass.

Technically ultra-competive environments usually trigger a similar response in the body anyway, just the method of the trigger differs.(music, meditation, rituals, etc)

And the technically technically if someone who had equal or greater amounts of fast twitch muscle fibers compared to Usain Bolt could run faster anyway, Usain Bolt could set a new record probably if say a tiger was chasing him

So what I'm trying to say is your top speed is determined by ratio of fast:slow twitch muscle fibers, the adrenaline determines more how easily you can reach this top speed.

Imagine your goal is to get only the whole strawberries in a slice of strawberry-rhubarb pie, and still make portions for the other people who want pie. You'd have to have a very sharp knife, and know where all the strawberries are, and the condition of the pie must allow it. You'd make a twisting wild slice that was continuous from berry to berry, and still be able to call it representative pie-sharing. You'd be able to keep all the whole strawberries for yourself, and call it a democratic process for slicing the pie.

Or, for the fantasy minded

It is the ring of power, which many parties have used, and which (so far) none have the ability to destroy instead of use.

Yes, ideally is the problem here. Once in power, many people tend to want to stay in power. You think you're doing the right thing, so it should be you staying in power and not the other person. Additionally, you can take bribes… I mean donations… to increase your income, as long as you are in power!

Selenium biochemistry is also an interesting topic. Trace amounts of selenium are essential to the diet of, at least to my knowledge, vertebrate animals. I'm not aware whether or not other kinds of animals use it. In several of the enzymes that metabolize iodine-containing thyroid hormones, the amino acid cysteine which contains the R-SH (thiol group) is replaced with R-SeH. Thus creating the unique amino acid "selenocysteine" at the active site of the enzymes. The -SeH seems to be important in handling iodine in thyroid hormones.

Thus, selenium deficiency can mimic symptoms of iodine deficiency. Although the former is rare in humans. Grazing mammals can get selenium deficiency in areas with certain kinds of clay soils.

concourses are typically lower ceilinged especially right at the gates, the discussion was about the terminals. that photo of concourse C looks totally normal to me. And of course is nowhere near as claustrophobic as the actual aircraft.

From Wikipedia:

"On June 25, 2009, American singer Michael Jackson died of acute propofol and benzodiazepine intoxication at his home on North Carolwood Drive in the Holmby Hills neighborhood of Los Angeles, California."

"On August 28, 2009, the Los Angeles County Department of Medical Examiner-Coroner concluded that Jackson's death was a homicide.[2] Jackson had been administered propofol and anti-anxiety benzodiazepines lorazepam and midazolam by his doctor.[3] Murray was convicted of involuntary manslaughter in November 2011, and was released in 2013 after serving two years of his four-year prison sentence with time off for good behavior."

"Jackson had long suffered from insomnia, and had a history of using drugs in an attempt to help him sleep.[14] Jackson's physician Conrad Murray was present to help Jackson sleep and gave him various drugs including diazepam, ativan, lorazepam and midazolam while monitoring him by his bedside.[13] After several hours and several drug injections, Jackson was still unable to fall asleep, and, according to Murray, was repeatedly asking him for "milk", a term for the powerful sedative propofol, which Jackson had used in the past as a sleep aid. At 10:40 AM, with Jackson still not asleep, Murray relented to his requests and injected him with 25 milligrams of propofol diluted with lidocaine. With Jackson finally asleep, Murray testified that he left his bedside to go to the bathroom, and after returning two minutes later, discovered that Jackson was not breathing and had a weak pulse.“
