Friday Fun Thread for December 22, 2023

Be advised: this thread is not for serious in-depth discussion of weighty topics (we have a link for that), this thread is not for anything Culture War related. This thread is for Fun. You got jokes? Share 'em. You got silly questions? Ask 'em.

Related to @DuplexFields below, if you could create a system of weights and measures that would be used worldwide, what would you do?

The SI system is pretty good (and a vast improvement over the mishmash of units that they replaced), but IMO there's still room for improvement. The "kilo"gram is the most obvious failure with its extraneous prefix, a change of one Kelvin is too small to detect unaided unlike one second, meter, or kilogram, and the ampere and mole are just weird numbers.

My proposed system would keep water as the informal reference material, as well as the second. Everything else would change to match the new discoveries in the last ~150 years: I would keep the rotation of the Earth, the mass of an atom, and the density and freezing point of water, but replace the circumference of the earth, the force produced by electromagnetism, and the boiling point of water with absolute zero and the elementary charge as follows:

Dimension Value Original Metric Derivation
 New Derivation
Time 1 s 1/(24 * 60 * 60) day No change
Length 2.71 cm 1/(40000000) circumference of Earth A 1x1x1 cube of water masses 1
Mass 19.93 g Water has density 1000 kg/m^3 10^24 carbon-12 atoms has mass of 12
Electric Current 160.3 mA Magnetic force between wires 10^18 elementary charges per second
Temperature 2.7316 K 100 degrees freezing-boiling
 0 is 0, freezing is 100
Amount 1 Atoms per gram None
luminous intensity ?? Whatever.

Do you have any improvements to the metric system you can think of? Any other changes you'd like made?

Do you have any improvements to the metric system you can think of?

Well, its base unit of measurement is fucking stupid. There's a very good reason that every pre-SI system of measurement, including the Chinese one (which was metric before the imposition of SI), has its two dominant units of length at 30cm (1 foot) and 3cm (~1 inch)- because it's meant to be human-scale.

Going off of something not relevant to the way most humans use measurement, like the size of the Earth, is a deficiency.

Nobody copies the French, and the French copy nobody- because the things they come up are weird and kind of batshit. Let them impose their standards at gunpoint (which is ultimately how SI spread across the Continent) and you're going to have a bad time- at least decimal time was too weird even for them.

What is this place?

This website is a place for people who want to move past shady thinking and test their ideas in a court of people who don't all share the same biases. Our goal is to optimize for light, not heat; this is a group effort, and all commentators are asked to do their part.

The weekly Culture War threads host the most controversial topics and are the most visible aspect of The Motte. However, many other topics are appropriate here. We encourage people to post anything related to science, politics, or philosophy; if in doubt, post!

Check out The Vault for an archive of old quality posts. You are encouraged to crosspost these elsewhere.


Why are you called The Motte?

A motte is a stone keep on a raised earthwork common in early medieval fortifications. More pertinently, it's an element in a rhetorical move called a "Motte-and-Bailey", originally identified by philosopher Nicholas Shackel. It describes the tendency in discourse for people to move from a controversial but high value claim to a defensible but less exciting one upon any resistance to the former. He likens this to the medieval fortification, where a desirable land (the bailey) is abandoned when in danger for the more easily defended motte. In Shackel's words, "The Motte represents the defensible but undesired propositions to which one retreats when hard pressed."

On The Motte, always attempt to remain inside your defensible territory, even if you are not being pressed.


New post guidelines

If you're posting something that isn't related to the culture war, we encourage you to post a thread for it. A submission statement is highly appreciated, but isn't necessary for text posts or links to largely-text posts such as blogs or news articles; if we're unsure of the value of your post, we might remove it until you add a submission statement. A submission statement is required for non-text sources (videos, podcasts, images).

Culture war posts go in the culture war thread; all links must either include a submission statement or significant commentary. Bare links without those will be removed.

If in doubt, please post it!
