I actually think "October Sky" was a better movie. A lot of overstatement in the not-so-hidden agenda behind "Hidden Figures".
At the current point in history, white women don't count as much as any person of color. Or at least that is what the pop culture and media are pontificating. It doesn't matter that minorities were instrumental in the moon landings. That will be overlooked and the "important" issue will be that no black astronauts were there. Or transgender ones either I would guess.Quote:

But people still do it thinking they are making some sort of improvement.
I liked the alien movie "Arrival". The final message decoded was "Use the weapon." It took a specially trained linguist to figure out what the alien message was. There was some drama about the message as "weapon" and "tool" meant the same to the aliens.
History - the study of past events, particularly in human affairs.
Past Events is the key.
I am not saying teaching "remainder" is wrong or bad idea. They had to do that, because they usually do whole number during those grades.
As for me, 3rd (to some 4th) grade division was very confusing.
15/4 = 3 R3

Ugh. 15/4 = 3.75. There is no remainder.
On a related note, I always hated fractions. The concept always seemed so antiquated even when I was in school. Do other countries still use or teach fractions? I?d much rather just use decimals.
Okay, shifting the conversation just a little.
All the young people of today will only be using their calculator function on their phone.
Math will be just to check if they made some input error by powers of 10.
So, what does the calculator say when 15/4 = Well, it says 3.75.
Remainder calculations fail.
Any Questions?
Though I do remember in 3rd grade, my teacher told us the reason we had to learn long division was because we wouldn't always have a calculator on us to punch in the numbers. :rolleyes:
I've found that people not good with fractions are typically not good with numbers in general. Fractions are important.Quote:

Don't like fractions, then you are not rational or is that irrational?

Fractions are not important, decimals are important. Engineers and machinists do not use fractions. Only trades where accurate measurements are not critical use them like in carpentry.
Are the engineers and machinists gonna build your house?Quote:

65 3/8!! Limit order at 65 7/16!! And fill!
That crap disappeared after 2000.
Division remainders are VERY important in Computer "programming". I can't tell you how I know this, but they ARE.Quote:

My father was a Tom Lehrer fan (and made me one) who was a great singing comedian from the 60s.
In the 60s a "new math" was introduced which is what I (and most of you probably) learned.
Here was Tom Lehrer's take on the old, new math.

Ps. I can remember doing base 8 math in 5th grade, which ties right into this video!

Goes to show that no matter what you learn, there will always be a "newer" math. I actually learned what Tom presents as new math. It took me a second to understand what he presented as the classic method, which really isn't different, just annotated in reverse order. I cant remember ever seeing how my Pops would have done such a problem, I think he just converted his habits to the methods I learned, but I just don't know for sure. What is being taught as new math now is quite revised, typically graphical, yet still retains the idea that it is more important to understand what you are doing that getting the right answer.Quote:

I can concede that point. I was using a bit of hyperbole. However, most of the engineers that I have worked with, mostly mechanical and electrical use the decimal for calculation. And in machining it was all done to the 1000th or 10,000th in Imperial or done in metric, which is what I used mostly.Quote:

Oh yes! Tom Lehrer.
I learned the elements from his song:
https://www.youtube.com/watch?v=yaFxrYEDmCs
There's antimony, arsenic, aluminum, selenium,
And hydrogen and oxygen and nitrogen and rhenium,
And nickel, neodymium, neptunium, germanium,
And iron, americium, ruthenium, uranium,
Europium, zirconium, lutetium, vanadium,
And lanthanum and osmium and astatine and radium,
And gold, protactinium and indium and gallium,
And iodine and thorium and thulium and thallium.
There's yttrium, ytterbium, actinium, rubidium,
And boron, gadolinium, niobium, iridium,
There's strontium and silicon and silver and samarium,
And bismuth, bromine, lithium, beryllium, and barium.
There's holmium and helium and hafnium and erbium,
And phosphorus and francium and fluorine and terbium,
And manganese and mercury, molybdenum, magnesium,
Dysprosium and scandium and cerium and cesium.
And lead, praseodymium and platinum, plutonium,
Palladium, promethium, potassium, polonium,
And tantalum, technetium, titanium, tellurium,
And cadmium and calcium and chromium and curium.
There's sulfur, californium and fermium, berkelium,
And also mendelevium, einsteinium, nobelium,
And argon, krypton, neon, radon, xenon, zinc and rhodium,
And chlorine, carbon, cobalt, copper, tungsten, tin and sodium.
These are the only ones of which the news has come to Harvard,
And there may be many others but they haven't been discovered.
I don't understand .5 of that.
But you get the pi of it!Quote:

If fractions blow your minds, let me tell you about isotopes.
Numerical calculations nearly always incorporate rounding, requiring evaluation of significant figures. Fractions do not.
But I am not a theoretical researcher. So I use decimals. And I wish the Chinese company that made my drill bit assortment used decimals also.
1/8 = 1 divided by 8 = 0.125Quote:
