  • By the way, 1 tablespoon of peanut butter does not weigh 14.79 grams. 1 US tablespoon is a unit of volume that’s equal to 14.79 milliliters(mils). Grams are a unit of mass. In order to convert between them we need the density. Because the metric system is great, the density of water is 1g/mil, so 1 US tablespoon of water weighs exactly 14.79 mils. However the density of peanut butter is a bit higher, so the US tablespoon of peanut butter will weigh a bit more.

    Additional pedantry, yes I did have to write US tablespoon every time. A US tablespoon is 14.79mils, a metric tablespoon is 15mils, a traditional Australian tablespoon was 20mils although now they mostly use metric tablespoons.














  • Sure. Australia has had mandatory helmets since 1990, and there’s been endless studies and debates since then, it’s still ongoing. I could find no clear evidence that helmet mandates decreased overall harm over any timeframe.

    To quote a review I read from 2007

    The following general principles should have widespread support: (1) Any legislation (including helmet laws) should not be enacted unless the benefits can be shown to exceed the costs. Ideally, the benefits should be greater than from equivalent ways of spending similar amounts of money on other road safety initiatives.

    And their conclusion did not find a consensus other than

    A majority of brain injuries >AIS2 are caused by bike/motor vehicle collisions. Traffic calming, enforcement of drink-driving laws, cyclist and driver education, or other measures to reduce the frequency and severity of bike/motor vehicle collisions, may therefore represent more cost-effective ways of reducing serious head injuries to cyclists than helmet laws. Indeed, countries with the lowest fatality rates per cycle-km also have the lowest helmet wearing rates

    Given that, helmet mandates are a bad law that takes away our liberties for no proven benefit.


  • Why is a electric motor overheating dangerous? Surely any electric car is going to have a system to throttle itself if overheating is an issue, and it will need that with or without gears.

    The fastest accelerating electric cars are single speed, presumably because it’s not worth changing gear when you only have 2 seconds.

    I can see why it might be useful in specific product categories, but when it’s not helpful for price or performance or reliability, that’s going to continue to be niche. The real problem electric cars need to solve right now is cost and a gearbox isn’t helping with that.
