Ok so you’re trying to catch a moving bovine. You might be trying to catch them around the head, or the heels. But in either case, you’re moving yourself on a horse, and then also trying to capture something moving so it can be tricky to get your timing right.

For example. If you’re trying to heel a steer, there’s a very specific moment where you have to throw so the loop goes around both hind legs. So you have to get you/your horse/your steer in the right spot to get it done and then time it perfectly and it’s all very fast.

The twirling the rope gets and keeps it ready for when your moment appears.

Businesses dealing with a lot of cash transactions like casinos and laundromats are key for laundering money, not heard of mattress stores being used.

There is a much nicer way to break down exponents:

• Calculate 2838393^2
• Calculate (2838393^(2))^2 = 2838393^4 by squaring the previous result
• Calculate ((2838393^(2))^(2))^2 = 2838393^8 by squaring the previous result
• ... this produces all powers of 2 we need (2, 4, 8, 16, 32, ... 1024)

x^1087 = x^1024 * x^32 * x^16 * x^8 * x^4 * x^2 * x and all these factors were calculated previously (here for x=2838393).

You only need to square numbers, and at the end multiply a few numbers with each other. The computer stores numbers in binary anyway (so 1087 is 1024+32+16+8+4+2+1 for a computer), no extra steps needed to find the right factors.

(actually, for OP's original problem, a computer would directly use 72829 = 65536 + 4096 + ...)

I highly doubt the battery can last 25 years with its full capacity. Please explain :)

Also it needs to be said that tobacco products in most of Asia and are generally quite inexpensive, even relative to their local economies.

One of the big things that lessens tobacco consumption is dramatically increasing the price, usually through taxes, which is what you see in a lot of the western world.

There’s also the “cool” factor. The coolness of smoking is far less in the west than it was 100 years ago, 50, even 20. But in most of Asia, it’s still pretty cool—and coolness in Asia is arguably more important than it ever was in the west.

I agree completely, and I think it actually should be called an "aquired scent" or "aquired flavor" rather than taste. Most people react first to the appearance of the food, then scent of a food (although those two sensory inputs are probably happening at the same time), then the mouth-feel and temperature, and lastely the actual taste.

See https://diplomaticacademy.dfat.gov.au/

A bachelor's degree is usually required.

A master's degree may be required.

Several years of experience as a researcher, consultant or program administrator may be required.

Foreign language fluency typically required

Foreign service officers are accepted on the basis of competitive examination.

That's making a huuuuuuuge presumption about logistics. It would be very expensive to roll out on a scale that would make adoption reasonable.

Tesla Superchargers are barely that widespread and that's a much lower impact solution than swapping our hundreds of pounds of battery cell, and has alternate options like charging at home.

Then why remove the comment? 😂

There are often shortcuts that can be used to make the problem easier. For example the fact that:

>(x^(a))^(b) = x^(ab)

Using this knowledge you can break down the exponent in your example, by finding its factors:

>67 * 1087 = 72829

1087 is still a bit large, so we can use another trick:

>x^(a) * x^(b) = x^(a+b)

And for example break it down to:

>500 + 587 = 1087

Using all this we can then perform the calculation:

>(2838393^(500) * 2838393^(587))^(67)

Which is a lot less daunting. It could probably use other rules to break it down further, but this is the general concept.

Nice image, shows that no country is at 100%. Take a look at it.

As I understand it, car batteries are arranged in packs of serial or parallel configurations to intentionally harness the resistance of serial or parallel to achieve desired voltage.

Thus using multiple batteries (and the resistance introduced by serialization or parallelization) gives the designer some control over the voltage.

Whether this is a side effect of needing multiple batteries for other reasons or a specific desired feature, I don't know, but it reduces the need for resistors.

Diplomats are people that represent a country and the country's interest in conversations with other representatives or leaders. They get cool passwords because they need to communicate back with the country they're representing to ensure smooth negotiations and relations.

You often need to work for the government, especially the country's foreign ministry (or equivalent) for a while before you're trusted with the power to represent the country

Computers do math operations, so a “big number,” particularly when converted to binary, is not much more demanding than a small one- the electrons just need to flow through a circuit that tells them what to do, and twice or ten times as long isn’t usually apparent on a human scale. To me, it’s equally or more interesting how a human brain is so efficient at some kinds of calculations, particularly abstract ones when developed, but only ever treats numbers as meaningful proportional to what their size represents versus the information encoded in them, which can be much less.

There are lots of people here making good points about safety but there are many reasons as to why EVs are built the way they are. One of which is just physics.

TLDR: Sorry this isn't short, batteries and stuff aren't easy to ELI5 but I think this works? (Other people feel free to correct if this is bad)

Batteries store a potential energy difference - this is a tiny amount - need lots to get correct energy.

After correct energy is achieved, tiny capacity = no range = stack EVEN MORE batteries.

Wires create resistance - loss in energy = bad. Modular connectors = more wire = bad.

Make pack big single block = less wires = less loss = more range = good

​

First, some battery background. A battery stores energy, for a simplified example: If I hold a bucket of water over my head, with an empty bucket at my feet, there is a potential difference in energy between the two buckets. The water in the top bucket wants to go down to the floor, and I will catch it in the bottom bucket to reuse it/recharge.

This is our full charge, our maximum voltage/difference, when all the energy is ready to move but not yet moving.

I pour the bucket out and all the water is at the bottom bucket and none in the top, the water cannot go down any further and we have no voltage/potential falling energy**.** The time it took for the water to flow down would be our capacity. (very simplified)

​

The energy is very small and we need lots of these together the create the required high voltage 300+V sometimes. (This is wired in series) However, the time it takes to pour this out does not give us that power for very long, we combine that first block so we have many buckets pouring one after the other (this is wired in parallel)

We need these modules to be an exact size of series to get the car to run, and a size of parallel to give our range. Some cars are built like this in the factory, where each module is separate. (For an EV I helped design and build we need nearly 100 individual batteries in series to get the movable energy, but this would give us a range of only a few kilometres so we stack 50 of those 100 battery modules together)

Then we get into physics and materials. Engineers use the modular method to design and build the packs, but this is why they might not be modifiable after they are built.

Electricity is most efficient when it goes short distances, if you have to run a long way you will be out of energy by the time you get to your destination, this is like electrical resistance. When building an efficient car we don't want long distances of cable. If I want to swap my battery I need to make all the modules separate, i then need to run lots of wires to a single point and then have a big High Voltage connector to join them to the other parts of the battery pack and to the entire car. Multiply that by 100x and you have lots of metal in the way of our flowing electricity causing resistance and taking away our power as heat instead of spinning wheels.

EV designers make the packs as much as one piece as possible to stop having connectors and resistance. Also the more parts that move and rub together are just more parts that can fail and need to be replaced. The best part is no part. So combining everything into one solid brick is more reliable, safe, easy to manufacture, and also more electrically efficient. This is one of the many reasons as to why some EVs have so much better range than others with the same size battery on paper.

​

I hope my examples were understandable and somewhat accurate. There is a lot of advanced engineering that goes into making finished products like cars and adding new technology makes it even harder to explain/understand!!!!!

hi. nobody here. thank you for acknowledging atypical use cases that need to be considered as more typical if EVs are to be utilisable as general replacements for ICE vehicles particularly in less densely populated regions or for longer trips.

not everyone has access to charging infra at destinations. not everyone can charge where they live or work. not all grids can handle the additional base load of EV charging (looking at you, texas).

swappable batteries would also radically lower vehicle and battery fabrication costs, by the way, not to mention eliminate a worry every li-ion device nowadays has that didn’t use to be a worry: what happens when the battery’s lifespan is breached and capacity craters.

Modern computers can perform many millions of operations per second thanks to how tiny their components are. Computing isn’t a problem for computers, it’s what they do.

Thanks for the explanation, i was really curious about this but I couldn't find anything online

Because unlike Europe and the US, there hasn't been a strong anti-smoking movement in those countries. The same things that kept us smoking for so long (political reluctance, lobbying and financial interests) are still in full power in Asia.

Asians dont smoke more than Europe or the US did up untill deep into the 80's
