Aluminum is much harder to weld than steel, primarily because it conducts heat faster, and has a lower melting point. This gives you a smaller "window of workability".

New Hampshire is the only US state to have no laws requiring adults to wear seatbelts. However, in many other states (such as Massachusetts), it’s a “secondary offense”, which means you can’t get pulled over for not wearing one, but if you get pulled over for a primary infraction, you can get cited for not wearing a seatbelt.

The tallest oil platform is 2100 ft tall! It’s called the Petronius Compliant tower, and is in the Gulf of Mexico. Most of it is under water though.

If clench my face really hard (kindof like I’m pooping), and wiggle my jaw, it works much better to clear my ears when I’m diving.

There’s this restaurant called Bali in Curacao that’s not worth going to.

If you don’t check in to your international flight more than 45 minutes before it leaves, they won’t let you on. On the upside, they can usually reschedule you for free.

The front seat of a Uhaul cabin can fit 5 people if you really try.

The building manager of The Stud (student center at MIT) is named Tim Woods and he can be pretty reasonable once you get to know him.

If you have a vertical plank of wood holding back water (ie, in a rectangular tank), the center of torque is at 1/3 the height of the water.

In economics, there’s this thing called the “productivity J curve”, where basically, after a new technology is discovered, “productivity” (as measured via GDP) will stagnate, because free capitol is being invested into the new technology (ie, building railroad lines, integrating AI infrastructure, etc). But then, once these shorter-term investments pay off, GPD rises faster again, overcoming the rate of decreased productivity.

There are two styles of cross country skiing. There’s “Classic”, where you mostly keep your skis parallel to each other, and mainly use your arms. Then there’s ”Skating”, where you point your toes outwards and drive yourself forwards by pushing your legs outwards. Classic is more intuitive, but generally requires better packed/more consistent snow.

Apparently Oxford has a secret “night climbers” club where people climb the walls + towers + roofs around Oxford. It seems to have a bigger focus on athleticism.

The Estonian flag looks like the average landscape in Estonia: White snow, black trees, blue sky. Look it up, you’ll see what I mean!

The ideal strategy in Ticket to Ride is probably to hoard cards at the beginning of the game (higher locomotives/card average, and you preserve optionality as long as possible). Also, start with game with fairly few tickets, and make sure they all can be linked together. People usually undervalue the utility of just building lots of roads and going out of trains. Also, in the EU version, Palermo to Moscow is the best long-route since that part of the board is much less crowded.

Apparently most countries other than the US have interest free investment accounts with no restrictions on what they can be used for (Canada has TFSA, UK has ISA). The limits are higher or comparable to in the US. The US has Roth IRA, but that has super strict limits on how you can withdraw from it, usually is just for retirement savings.

Estonia, Finland, and maybe a few other countries are all in the same free-market energy pricing scheme. Due to extremely cold temperatures as well as less supply (I assume Russia/Ukraine stuff), energy prices are now such that running a small space heater for one day would cost ~€150. God bless America, and her oil.
