and yes I'm familiar with that famous identity and how it's a way of expressing rotation in the complex plane.
Wow…
With all THIS info, we can REALLY impress our friends!
On your device.And the Ω shortcut is "ALT" 234
Along with the ° is "ALT" 0176
You forgot the most useful units to really impress your friends !The following are common units and their abbreviations. Note that unit abbreviations are case-sensitive. While some units can be understood when written incorrectly, some have a completely different meaning if the wrong case is used. Avoid any possible confusion or ambiguity and use the correct case.
A - amps, a unit of current. Named after André-Marie Ampère.

m - Meter, a unit of distance in the generally admitted International System of units
g - Gramm, a unit of weight in the generally admitted International System of units
°k - Kelvin, a unit of temperature in the generally admitted International System of units, also °C, shifted by 273 °K into common tempeatures on earth.
A gram, g, is a unit of mass, not weight. Weight is a force.g - Gramm, a unit of weight in the generally admitted International System of units
There is no ° symbol when expressing a temperature in units of kelvin and it uses an upper case K.°k - Kelvin
Ok, you and Crossy win!The gram ceased to be the base SI unit of mass in 1960 and was replaced by the kilogram, kg, while the gram became a derived unit of the kg.
The world kelvin is also not capitalised, the same as "metre", "watt", "kilogram" and "gram" except when used in a title or at the start of a sentence.
Ok, you and Crossy win!
I still feel more comfortable using them with the wrong grammar, than to keep using imperial units, remnants of a medieval age.
You are not only confusing the French.Aren't they now called "US customary units" and are subtly different from "imperial"?
We Brits use an eclectic mix of metric (fuel in litres) and imperial (distances in miles) etc. etc. I think we do it just to confuse the French!
I couldn't get replacement doors for our place in the UK, turns out our doors were "metric" and the standard 6'6" x 2'6" doors were just the wrong shape.
I could write three pages about traditional units of measure and how they were derived. Why they fractionally divide in ways that create comfort, how that feet and inches scale out to the Golden Mean and how - inexplicably - Vesuvius and Michelangelo demonstrated ratios in nature that scale out in quarters, eighths and fifths.using imperial units, remnants of a medieval age
Some things, not everything.because everything in nature works that way
???That we arrived at 10-base math isn’t surprising. That we insist on using it as measure for volume or for furniture design is surprising, since “we” - by nature- see things in halves, quarters, fifths, twelfths because everything in nature works that way.
You must have worked for the the Washington Post! ?I once worked for a company that shall forever remain nameless, but we were designing safety critical systems used to move large numbers of people...
Anyhow, the Chief quality control honcho once told me that we only check documents and reports for correct spelling, font, width of margins, and that documents absolutely must conform to the official template. We never check facts, figures, or actual content.
So total nonsense gets a pass. But woe betide anyone that dares to submit something with a slightly displaced heading.
Oh so close…A gram, g, is a unit of mass, not weight. Weight is a force.
The gram ceased to be the base SI unit of mass in 1960 and was replaced by the kilogram, kg, while the gram became a derived unit of the kg.
There is no ° symbol when expressing a temperature in units of kelvin and it uses an upper case K.
e.g. it's 273 K, not 273 °K and not 273 °k.
The world kelvin is also not capitalised, the same as "metre", "watt", "kilogram" and "gram" except when used in a title or at the start of a sentence.
You are thinking empirically, logically, computational. You are missing the point. You are thinking it’s merely a matter of computational efficiency to be 10-based:But, pardon me, only US citizens think in fractions.
It is just unnatural to use a 10-base math together with fractional measurement units.
A regular bottle of wine is 75cl, nobody in Europe would call it a 3/4l bottle.
Fingers have nothing to do with how ‘we’ arrived at 10-base numbering and math. We arrived there because it creates computational possibilities in a linearly predictable and repeatable fashion. (Humans do have 8 fingers btw)humans had 8 or 12 fingers.
He understands that math isn’t made up of merely a 10-based place-to-value system. It’s the reason some beautifully crafted architecture feels ‘sterile’ or uncomfortable if not somehow cold, while others even those in a similar style or discipline feel relaxing and/or inviting and welcoming.Natural growth and decay patterns in life (and many parts of the natural physical world) follow a natural exponent e, and the emergence of π of course should be obvious in nature - there's a reason it pops up in so many physics formulae.
Other life tends to display the golden ratio, φ, or other similar irrationals like the silver ratio and we see this in the way Fibonacci numbers pop up in all sorts of places, e.g. the structure of seed placements on flowers, or leaves around a stalk or the way gastropods shells grow.
Indeed, although I didn't forget it, I just didn't mention it. Like I didn't mention dozens of other units.You forgot Celsius as in degrees Celsius which is always capitalized.
Bananas are made in thirds....see things in halves, quarters, fifths, twelfths because everything in nature works that way.
Over here liquor and wine is now sold in 750ml (not 75cl) bottles (~25.4 oz), which is conveniently close to "a fifth" or 1/5 U.S. gallon (25.6 oz), which was the standard size before they realized they could swindle us out of ~0.2 oz of spirits by simply relabeling the bottle in metric and charging the same price.A regular bottle of wine is 75cl, nobody in Europe would call it a 3/4l bottle.
