It’s very easy, just rehearse these phrases… and try use them with confidence in every conversation.
- Use “canonical” when you mean “usual” or “standard.” As in, “the canonical example of talking like a physicist is to use the word ‘canonical’.”
- Use “orthogonal” to refer to things that…
"Under the same circumstances, and the key words are ‘the same circumstances’ yes, I would do it again. We were in a war for five years. We were fighting an enemy that had a reputation for never surrendering, never accepting defeat. It’s really hard to talk about morality and war in the same sentence. In a war, there are so many questionable things done. Where was the morality in the bombing of Coventry, or the bombing of Dresden, or the Bataan death march, or the Rape of Nanking, or the bombing of Pearl Harbor? I believe that when you’re in a war, a nation must have the courage to do what it must to win the war with a minimum loss of lives." - Theodore "Dutch" Van Kirk, who passed away yesterday at the age of 93. He was the navigator on the "Enola Gay" for the Hiroshima atomic bomb mission, as well as the last remaining crew member. Thank you @wwii_pictures for bringing this airman’s passing to my attention.
For 17 years, James Doyle was a nuclear policy specialist at the Los Alamos National Laboratory. Then he wrote an article that made the case for getting rid of nuclear weapons. After that, his computer was seized, he was accused of releasing classified information, and then he was fired.
The article, “Why Eliminate Nuclear Weapons?,” appeared in the journal Survival: Global Politics and Strategy, which is published by the International Institute for Strategic Studies in the UK. It’s not exactly a household name, but the journal has been a publishing venue for prominent academics and policy wonks since it was founded in the Cold War (hence, its rather alarmist-sounding name).
Doyle’s piece wasn’t an anti-government rant, but a lengthy argument that nuclear weapons had lost their strategic utility and value as a deterrent, that getting rid of them would enhance international security, and that this was an ideal point in time to get serious about global disarmament.
Tungsten evaporated crystals and 1cm3 cube (
Tungsten is an incredible material. It is dense and hard, and it has the lowest vapor pressure and highest melting temperature of all metals. This combination of properties makes tungsten extremely valuable for a myriad of applications, while at the same time creates great challenges in the processing of the metal.
As a child, I was fascinated by how things work and spent a lot of time taking things apart. As with most budding engineers, I rarely reassembled them. Incandescent bulbs were one of my first quarries, carefully disassembled to reveal a hidden treasure: a tungsten filament. It was amazing that this tiny wire could be heated to white-hot temperatures to produce light.
Also at an early age, I was introduced to vacuum tubes, and to this day they are magical in my eyes. When a tungsten filament is heated in a vacuum, the electrons near the surface become energetic enough to be emitted into the surrounding space. Additional tungsten conductors, in the form of grids and plates, can be added to the bulb, and the electrons can then be manipulated to switch, rectify and amplify These electronic switches were crucial in the development of modern electronics.
Tungsten at a Glance: Name: From the Swedish tung sten, meaning heavy stone. The symbol is from mineral wolframite, from which the element was originally isolated. Atomic mass: 183.84. History: Isolated in 1783 by Spanish chemists Juan Jose and Fausto Elhuyar. Occurrence: China has 75% of the world’s tungsten ores. Appearance: Silvery white metal. Behavior: Tungsten has the highest melting point and highest boiling point of all metals. Uses: Tungsten is used in high-temperature applications such as heating.
It’s Elemental: Tungsten

Starfish Prime was a high-altitude nuclear test conducted by the United States on 9 July 1962 as part of Operation Fishbowl over Johnston Atoll. It was successfully detonated at an altitude of 400 km (250 mi) at 09:00:09 Honolulu time.
Starfish Prime’s electromagnetic pulse was much larger than originally expected and drove much of the instrumentation off scale, as well as causing electrical damage in Hawaii, which was about 1,445 km (898 mi) away from the detonation point. It knocked out about 300 streetlights, set off numerous burglar alarms and damaged a telephone company microwave link.
I like this, but before anyone gets on the ‘EMP=end of the world’ train please see:
