That's inaccurate. Egypt was shutting down Straits of Tiran which started the war:

practicemaths··on A site that tracks the price of a Big Mac in every US McDonald's
Economic theory would suggest that you price your product where it will give you the maximum amount of return or profit.

So even if increasing price might lower total number of sales the total dollar amount might actually be bigger than before.

If you read the history of the conflict, Palestine only exists today because Israel gave them land that they (Israel) won from wars that neighboring countries started.

Additionally, Israel called dibs first, that is Palestinian/Arabs could have declared themselves a country as soon as the British mandate ended but chose not to. Instead Israel did first and was attacked by neighboring countries which caused the majority of the Palestinian diaspora.

practicemaths··on Ex-Google CEO Eric Schmidt Is Working on a Secret Military Drone Project
Does Russia have access to said equipment in sufficient quantities?

Having stats in a spreadsheet is a lot different than what the tool is actually in the field.

i.e. equipment manufacturered to code, inspected, and maintenance schedules followed.

practicemaths··on The Magic of the Blackboard
My Calculus Professor liked blackboards because he could slow the down material for everyone.

He told me he started off with slides and stuff and thought it was going to be all slick and cool for everyone. Then he eventually realized it just goes through material too fast.

practicemaths··on IRS to begin trial of its own free tax-filing system
My experience has been that it can be relatively faster.

That is, the last time I filed online it took I think practically a year before they got to it (I think the year of the pandemic)

I figure there's so few people filing by mail these days that they're able to process them faster than the huge amount of online filing.

I'm guessing they're separate teams (online vs mail). However I have no idea.

Regardless mailing has worked better for me the last couple years.

Additionally I do not have to use the third party ID verify thing (might just be for accessing information on irs.gov) that I am just sure is going to have a breach and can not for the life of me fathom why our government (Federal) needs a private company to verify the identity of a citizen via government (State) resources.

practicemaths··on "Are We Automata?" by William James (1879)
I suppose for meeting Gen. Ed. requirements more history and philosophy classes with a focus on where certain Math and Science comes from could be great.

Additionally math courses for the non-stem majors that focus more on the history and importance of something, say the quadratic formula, instead of applying it/remembering it without much context from where it came from could help out a lot of non-stem majors with their math requirement.

However I think it boils down to interest and a degree of time whether or not someone in a stem field feels compelled or not to pay attention and learn where their math tools come from or the experiments that built the respective sciences.

That is, I've found while stem classes may not focus on the above, they do cover it and for the more enthusiastic and self motivated student right there in their books to read about.

I've also found professor's that love this stuff too, which I've found pleasure in them sharing these stories when they can.

I just file my taxes by hand and mail it in. Somewhat less concern with 3rd parties holding my information and losing it to leaks/hacks.

It is free.

A little obnoxious but the forms do have instructions/directions.

practicemaths··on A few financial firms now own a significant portion of the American economy
Well good luck to them then.

If I'm tracking comparable values correctly Harvard has around 50 Billion while Blackrock alone has over 9 Trillion.

practicemaths··on Why We Find Some People Boring
"find that exceedingly boring irrespective of how much energy and excitement they might display for their trivial interest."

" I have also noticed those boring people seem equally bored, disgusted, or hostile to things outside their focused area of attention."

Not trying to be mockingly rude but is not the thing you find boring in others the exactly same thing you're doing?

practicemaths··on The Hybrid-Car Dilemma
> The problem carmakers face is that hybrids involve all the complexities of internal combustion and battery power put together. Building them “takes a lot of time and a lot of money,” Sam Fiorani, the vice president of the industry research firm AutoForecast Solutions

There's no dilemma, the issue is obvious right there. It makes more sense to invest in 100% EV now for decades of return vs Hybrid research that has about 20 years left of potential return.

practicemaths··on Revitalizing US Navy Shipbuilding
Centralized what exactly for efficiency in defense spending?

edit: downvote if you want but it's rather rude to do so with out providing an answer to my question. It comes off more like you're offended that your assumption in thought is being questioned.

practicemaths··on Teaching C (2016)
What's wrong with C? I'm teaching myself with Ritchie at the moment. Seems fine so far but I'm also more interested in embedded systems.
practicemaths··on High school math doesn't prepare most students for their college majors
And many teachers have continual education.

That means the implementation of common core is also upon teachers with decade(s) of experience being told to teach differently.

Regardless, if your child has a nack for maths that is a great advantage over the other children and worth investing in since so few people bother to learn it at all.

Additionally it leads to better reasoning and logic in other academic and professional settings as well. Which means a better chance at a higher income and ability to sustain and secure their livelihood and thus afford having their own children possibly. Which means a better chance for continuation of a little bit of yourself.

practicemaths··on High school math doesn't prepare most students for their college majors
I do not have a child or direct experience with common core.

Personally I suspect issues lie more in teachers themselves not being taught correctly than the actual concept behind common core though.

From what i can gather it is trying to introduce the concept of factoring earlier which in my opinion makes sense since that is really useful in Algebra and above.
