What do you know today that you didn't know yesterday?

Boru

Potential energy released is proportional to drop height and the mass dropped.      1000m is about 20 times as high as Niagara.    Mercury is 13.5 times more dense than water.     If the same volume of mercury flow over your 1000m fall as water flowing over the 50m Niagara,   The energy released would be 20 X 13.5 =270 times as great.

So a 1000 m mercury fall flowing at the same volumetric flowrate as Niagara will release as much energy every minute as Niagara Falls would releases every 4 and half hours.    

That’s the energy of a hiroshima bomb about every minute.

Interesting. What if it was chocolate custard?

What if it were neutronium, and dropped from the height of the edge of the atmophere?

Well, now you’re just being silly.

Apparently I can sleep past 4 in the morning. Now if I could only figure out what I did differently last night...pretty sure this is a one off.

Reminds me of the boxer skit from Monty Python.

"The boxer gets up every morning at 3 AM and jogs the twenty miles to Surrey and back, then goes back to bed. Nobody knows why."

On a deeper level, Minus One is a refutation of Imperial Japan's old-fashioned notion of sacrificial military heroism.

It probably reflects anxiety in some parts of Japanese society regarding the re-militarization of Japan, ostensibly as part of forces of democracy aligned with the U.S. against China,  but attended by a cultural trend, gathering force and promoted by the ruling liberal Democratic Party since about 2005, towards the renewed glorification of Japan’s imperial militaristic past up to and through the end of WWII and the removal of pacifist provisions put in Japanese constitution placed there after Japan’s defeat in WWII.

It may also reflect a latent fear in Japan that if Japan does fight China again, the war between Japan and China will go nuclear just as the war with U.S. did.

G-1 is a manifestation of the Japanese people's angst on finding out the government and military had lied to them about the progress of the war for years.

Before clocks, there were candle clocks, that when burned, effectively indicated the passage of periods of time especailly indoor and at night.

To set an alarm, you just pushed a nail into the desired point and the nail would fall and clank on the metal holder at that time.

Something tells me that Boru still uses this clock
teachings of the Bible are so muddled and self-contradictory that it was possible for Christians to happily burn heretics alive for five long centuries. It was even possible for the most venerated patriarchs of the Church, like St. Augustine and St. Thomas Aquinas, to conclude that heretics should be tortured (Augustine) or killed outright (Aquinas). Martin Luther and John Calvin advocated the wholesale murder of heretics, apostates, Jews, and witches. - Sam Harris, "Letter To A Christian Nation"

Wait, what…? Like I’m the ONLY fucker here that uses a candle-nail-dropping-clanky-metal-tray-type alarm clock. Sheesh.
