> However, an electron, unlike a planet or a satellite, is electrically charged, and it has been known since the mid-19th century that an electric charge that undergoes acceleration (changes velocity and direction) will emit electromagnetic radiation, losing energy in the process.
If I take a small piece of matter and shake it for a long time, then don't all its electrons and protons emit electromagnetic radiation and lose energy?
To me it seems the rest of the article, i.e. probability density, also means that the electrons undergoe acceleration because their location changes.
Sounds interesting. Let's say the software is a web backend. Can you deploy it like this with zero downtime? So that the new version starts, new traffic goes to it, and the old version handles its active requests to completion and then shuts off.
I've written an image processing tool in Rust, where running a large image downscaling test with a release build takes 2.0 seconds, and with a debug build it takes 18.7 seconds. So most of the time during development I compiled in release mode, because it was actually faster overall.
For many applications debug builds are fast enough, but their runtime performance is already so slow, that I hope they don't get even slower.
Thank you for your great explanation. I've read the documentation of re-frame, but I still can't figure out how it deals with reusable components and hierarchies.
Let's say I want to write a reusable datepicker component which sends an event like [:date [2017 1 16]] when the user clicks on that date. How can it send it to the calling component? The re-frame pub/sub message bus seems to be global, but what if I want to have several instances of the same component on the page?
The only solution I can come up with is to parameterize the component on instantiation, so that if I have a "person" component that uses the datepicker to set the day of birth of the person, the date-picker would be parameterized so that it would emit a global event such as [:set-person-day-of-birth <person-id> [2017 1 16]]. Is this how re-frame approaches hierarchies?

You're confusing central planning and science. Governmental politics and advisory is a form of central planning, and in that realm mistakes are shunned upon.
Science is a protocol that, if duly practiced, will evolve our understanding towards the truth. But the path is not straight. And science does not give any way for determining whether we have found the truth at the present moment.
That's why in proper science everything is in constant flux. For some people that's terrifying, so they prefer central planning and static advisory from above.
There's an interesting anecdote from Finland. A company called Copterline flew between Finland's Helsinki and Estonia's Tallinn for many years with two Sikorsky S-76 helicopters. The trip was over the ocean and took 18 minutes.
Sadly one of their copters crashed into the ocean in 2005, killing all 14 aboard. The reason was purely technical. The hydraulic steering system got stuck due to debris that had came loose from an inner coating. The copter was impossible to steer and started spinning around its axis, and spun 13 times until hitting the ocean.
It was the beginning of the end for the company. Later in 2008 they started again with two AgustaWestland AW139 copters. I was aboard once, and it was a fantastic experience. However, it boggled my mind how much even a modern helicopter vibrates. It's a wonder to me how copters can withstand the constant violent vibration. Apparently they can, except in rare cases.
In 2004 Copterline transported 75 000 passengers. If all flights were full (12 passengers and 2 pilots) it means about 17 flights a day, every single day.
Copterline went out of business in December 2008 because it was unprofitable. It's sad, because flying on a helicopter is a cool experience mortals like me usually can't experience without commercial flights.
