I think this is how my annual bonus is calculated.
At least I get the nice Christmas card every year.

I don't believe for a second that this is anything other than a brilliantly calculated and utterly cynical move from Nike to co-opt Kaepernick's protest.

But I find it hilarious that people are falling for it, especially the idiots burning their shoes.

So you were fine with Nike when they were doing actual evil shit like sweatshops and child labour, but you'll burn the sneakers (that you already gave Nike the money for) over an ad?

And liberals are just as bad on this. Nike are a big corporation who give 0 fucks about BLM. If you buy their shoes, you're supporting a company with terrible labour practices.

I'm not saying you should or shouldn't buy Nike shoes. If you want some shoes and they're good shoes and you're ok with their labour practices (or you feel that you not buying one pair of shoes won't make a difference), then buy them. Or if you don't like them as a company, don't buy them.

But don't lie to yourself and pretend that buying or burning Nikes is some kind of political statement.

That's an average speed of 146 mph!!!!

The use of pesticides "legally approved or unapproved" is not calculated in a lot of these studies.

At least with legalization. there puts some accountability towards what is used.

Can be! It depends on the contents of the container and how air-tight its construction and materials are. Generally materials packed for transport are supposed to be strapped or otherwise held in place so that they don't shift and upset the transport vehicle (see the 747 that crashed in the Middle East when its cargo shifted...). But that's just the stuff that was meant to be in the container. Every ship has to contend with the risk of water ingress. Un-contained water in a vessel forms a "free surface" and the so-called free surface effect applies. That's where that material can and will move based on gravity, often making a bad situation much much worse. Imagine water in a tank (itself a free surface) vs. water sloshing around the cabin of a plane. This is what usually causes ships to capsize: water gets in and isn't contained, so it can move tremendous amounts of mass anywhere it wants to go -- usually in the direction it's already going. Calculations of ship stability for things like cargo loading and ballast assume minimal free surface in the ship, because you have to. That's how ships stay upright and afloat.

How does this apply to lost containers? Depending on how watertight the container is and how well strapped in the contents are, some amount of water may get in and form a free surface. This free surface will move around until the container finds its equilibrium which may or may not be watertight and less dense than the water around it, which defines whether it floats or sinks and what direction it faces when it does.

A container with a lot of weight on one side but otherwise watertight will stand upright and perhaps still sink (like the one at the end of this video). A container with well-distributed weight would tend to end up flat. Whether it sinks or not depends on whether it's watertight and what its density is -- the weight of the container displacing ocean vs. the weight of the ocean it displaces.

Sadly, a significant number of containers end up at the worst possible density/displacement where they float just at or near the surface and lay in wait to devastate passing ships, regardless of the orientation of the container itself.

I still wear my old school Casio Data Bank 150 calculator watch.

Around here, fines for "burnouts" are calculated by the foot.

So wait...he talks about how important the weight is because it determines the load that can be carried. He does the weight calculations and then immediately starts talking about the cost of the truck and never finishes his weight analysis.

According to his estimation, the weight of the unloaded truck with trailer is 7 tons. If the batteries on a 500 mile truck weigh 8 tons then the total 15 ton vehicle is lighter than the ~17 ton average for a standard semi with trailer. I'd round up for the weight of the motors and since his empty weight calculation seems a tad low. So you can assume the weights of a Tesla truck and stardard truck are at least within spitting distance of each other.

Range is less of an issue since a driver is only allowed to drive a maximum of 11 hours in a 14 hour period. So assuming they drove a solid 11 hours at 60 miles per hour (since that's what the 500 mile range is based on), the standard truck can drive 160 miles further. But if you're driving 11 hours without a break, you're an idiot. And Tesla indicates that a battery can fully charge in under 30 minutes.

Last point, he estimates the battery cost alone will be $108K and $180K but Tesla has set the expected price of the actual trucks as $150K and $180K. Considering a traditional truck runs $80K - $150K, it seems the return on investment for a Tesla truck might be shorter than a traditional truck, given the economy of electric compared fossil fuel.

Great video though. Love all the math.

In the civilised world, "doing taxes" is one of those weird things you are aware of because of American TV.

In my entire working life, my interaction with tax amounts to looking at my payslip whenever my salary changes and ... that's it.

My tax comes off my pay automatically, I pay a flat Goods and Services Tax of 15% on everything I buy, and there are various other duties, levies, etc., all of which are pre-calculated and included in the listed price.

There are a few "tax refund" companies around that will try and recoup a tax gain, but most of the time it amounts to so little money it's not worth it.

wtf...why would calculators make sounds like that?
Can you imagine how annoying an office full of these would be?
