We usually use fractions, but sometimes we're forced to use decimals, usually when related to computers, since the usual fractions don't translate well to decimal.

Wait, what? You're saying that Americans preferentially use base-2 fractions (nearly) everywhere except on computers; on computers you preferentially use base-10, even though said computers are going to store the values as base-2? That's the funniest thing I've heard all week.

A feature of some English measures is unbiased division into three equal parts, e.g. Three teaspoons to the tablespoon, twelve inches to the foot, and twelve ounces to the pound (for one of several definitions of “ounce”).

Thirds don’t fit neatly into binary nor do they fit neatly into decimal. This is what the comment refers to.

I have a lot of junk in my kitchen drawers (admittedly a personal problem) and will opt for measuring directly from the bag into the bowl on a scale over digging around for that quarter cup every time.

Replace "convenience" with "low cost of equipping the kitchen" then.

A set of measuring cups and a digital kitchen scale probably cost about the same.

Just checked this with a quick search on Amazon -- most results are in the $15-20 range, with some available for $10 or less.

(I dare say there are probably very cheap measuring cups available, and for a scale you’ll have to fork out occasionally for batteries, if you want to split hairs.)

This is a reminder that the USA still held black folks as slaves in 1776. This was woven into American society from the very start. Recall that the Native Americans were referred to in the Declaration as "merciless Indian Savages", and have been systematically attacked and abused, also since the very start. If you're celebrating Independence Day today, this is what you are actually celebrating. It should be a day of…

Tunnel visioning on slavery is a pretty bad mindset. There are many facets to American society beyond slavery. It's almost impossible to imagine a person today who supports slavery. We've come a long way, and nobody is celebrating slavery.

This is implicitly what you are celebrating if you choose to worship the Independence Day.

No, it’s not. Before American independence the British crown held slaves. Prior to independence both SC and Virginia actually requested to pause or slow down the slave trade. They had to make this request to England and it was refused. The Declaration of Independence laid the groundwork for the eventual end of slavery that culminated in the Civil War. After US independence, Britain began to wash their hands of slaver…

> Before American independence the British crown held slaves.

Well exactly. And it was a practice that continued for many, many years afterwards. Arguably the early US economy was mostly built upon slavery. All that wealth created by people forced into labour who received no compensation for their hard work, but instead just enriched the slave owners.

It's selective history to ignore this and pretend that America was some beautiful egalitarian society striving towards anti-slavery from the start, and that any slavery that remained was solely the fault of the British.

This should be a day of shame and dishonor, if we're not being selective about history.

1812 – that's when Napoleon invaded Russia.

I think they were referring to the War of 1812. A war the US lost, and where the song "The Star Bangled Banner" comes from.

> I think they were referring to the War of 1812. A war the US lost

The outcome of history indicates the US won that war. Technically it was considered a stalemate. The US lost no territory, repelled a malevolent empire again, kept its economy & trade fully intact, and won numerous major battles throughout the war. In the following decades the US became an economic juggernaut, while the British Empire began to fade into the history books.

A supposedly mighty empire failed twice in less than 40 years to bring a small nation to its knees. Quite humiliating.

https://en.wikipedia.org/wiki/War_of_1812

- "In 1813, the US won the Battle of Lake Erie, gaining control of the lake, and they defeated Tecumseh's Confederacy at the Battle of the Thames, defeating Britain's largest Native American ally, a primary war goal."

- "In 1814, the British burned Washington, but the US later repulsed British attempts to invade New York and Maryland, ending invasions from Canada into the northern and mid-Atlantic states."

- "Attempts to smother American maritime trade failed, however, and soon both sides began to desire peace."

- "In early 1815, after a peace treaty had been signed, but before this news had reached the Americas, the US defeated the British Army near New Orleans, Louisiana."

- "Peace negotiations began in August 1814, and the Treaty of Ghent was signed on December 24, 1814. News of the peace finally reached America in February 1815 about the same time as news of the victory at New Orleans. The Americans triumphantly celebrated the restoration of their national honor, leading to the collapse of anti-war sentiment and the beginning of the Era of Good Feelings, a period of national unity. The treaty was unanimously ratified by the US Senate on February 17, 1815, ending the war with no boundary changes"

Rulers, drill bits, and wrenches typically use fractions of an inch where the denominator is a power of two, but circuit board design often uses decimal fractions of an inch. The holes in a breadboard are commonly .1 inches apart.

Then the whole mils thing...

Routing a PCB is like constantly flipping your ruler around: Old, classic through-hole parts are in inches/mills, while new, modern surface-mount parts are in millimeters. All electrical aspects (traces, spacing, lengths) are measured in inches/mills, and often the mechanical aspects are measured in millimeters (if the enclosure is not made in the U.S.). And if you use the wrong system, you engineering tables and formula stops working, the whole thing is out-of-context (e.g. measuring the gap in a differential pair in millimeters, the number makes no sense), and an integer becomes a float with three significant digits after the decimal point.

So here is the joke: The electronics industry is moving towards the metric system, one mill at a time. At least CAD programs have a button to switch between the two instantly.

Why would aliens work in base10?

Looks like they had 3 fingers per hand, so base 6 seems a likely choice. 6 works great as its divisible by 2 and 3. I wonder what base we would use if we (somehow) had a prime number of fingers. 2, 6, 30, 60?

The ancient Sumerian number system was base 6. Our units of time are still based on that.

60 seconds, 60 minutes, 24 hours.
