I have asked math teachers about this and they seem to be behind the line that it helps kids understand how they got to a solution. I am yet to see any credible research that illustrates that this improves skills or thinking or critical thinking.

I will admit, I do THINK about numbers this way. If I come across a problem that's too difficult to do immediately, I start breaking things up in my head.

Sometimes when I'm bored and walking I whistle, sometimes I recount the digits of pie, sometimes I recite the To be or not to be speech from Hamlet, sometimes I start multiplying (really)

2x2 = four
4x4 = sixteen
16x16 = uhhhh <<<< and this is where I start breaking it up --->16x10= 160
----->10x6= 60
------>6x6= 36

Then I have to remember the 36 as I add up the 6 n 6 for 12 dont forget the zero so it's 120 + 100 + 36
so it's 256

256 x256 is like 250x250 or 25x 25 (at this point it's helpful to think of quarters and money) and then add 36 (6x6)
so if there are 4 quarters in a dollar or 100, 25/4 = $6.25
then i need the zeros still

62500 + 360??? = 663? no that's not right, 65? Im losin' it somewhere in there, cant keep track a whole lot further without some paper in my hands or digital transcription (I'm trying to simulate what I actually think of)

>>>>>>>> 65k? estimation <<<<<<<<<
ALL that said, I do that but I learned math the old way and worked as a cashier for 5 years. I never would do regular calculations this way all the time, it's just handy for some fast math. It was easier to commit to memory a lot of my multiplications tables than it would have been to think through this stuff when i didn't know anything about it.

a lot of the education community shits all over the idea of memorization, but I think there's something to be said for it and would be interested if anyone had any studies of memorization as a teaching method and its efficacy.

I think you mean digital graphics editing! - I doubt any piece of that is real!

OK, hold the fucking phone here. This video is just a disaster. It is flippant and glossing over the facts of what actually happened. This story is a favorite of mine, so I have done a lot a reading on it.

This happened in 1983 (36 years ago).

>> Do planes seriously not have a fuel gauge?

There is specifically a digital fuel gauge processor on that plane, and it was malfunctioning. There was an inductor coil that wasn't properly soldered onto the circuit board. At that time, planes were allowed to fly without a functioning digital fuel gauge as long as there was a manual check of the fuel in tanks and the computer was told the starting fuel.

The problem is that fuel trucks pump by volume and planes measure fuel by weight. The fueling truck converted the volume to kilograms and then converted to pounds. He should not have used both. In 1983 ground crews were used to converting volume to pounds. The 767 was the first plane in Air Canada's fleet to have metric fuel gauges.

The line in the video "the flight crew approved of the fuel without noticing the error" glosses over how it is actually done. The pilot was passed a form that contained the numbers and calculations from the ground crew that stated that 22,300 kg of fuel was loaded on the plane. The math was wrong, but unless the pilots re-did the numbers by hand, there wouldn't be anything to jump out at them. He accepted the form and punched those numbers in to the computer.

The 767 was one of the first planes to eliminate the Flight Engineer position and replace it with a computer. There was no clear owner as to who does the fuel calc in this situation. In this case, it fell to the ground crew.

>> I would hope there is a nit more of a warning system than the engines shutting off.

If there was a functional digital fuel gauge, it would have showed them missing half their fuel from the start, and the error would have been caught. Because there wasn't, the computer was calculating and displaying the amount of fuel based on an incorrect start value.

That is another problem with this video. It states that "they didn't even think about it until ... and an alarm went off signalling that their left engine had quit working."

Fuck you, narrator asshole.

In this case, low fuel pump pressure warnings were firing off before the engines shut down. They were investigating why they would be getting these low pressure warnings when their calculated fuel values (based on the original error) showed that they had enough fuel.

>> I can't believe the pilot's were given an award for causing an avoidable accident.

The pilots did not cause it. They followed all the proper procedures applicable at that time, 1983. It was only due to their skill and quick thinking that the pilots landed the plane without any serious injuries to passengers.

They ran simulations in Vancouver of this exact fuel and flight situation and all the crews that ran this simulation crashed their planes.

"Bad math can kill you." Flippant, correct, but still not quite applicable to this situation. Air Canada did not provide any conversion training for dealing with kilograms and the 767. Not the ground crew, nor the pilots, were trained how to handle it. They were expected to "figure it out". That, and the elimination of the Flight Engineer position, set these situations up for disaster.

So here's my opinion.
I hate this.

Why you ask?
Because, while each producer has become the artist, none of them respect the music. I understand this is the assignment. But it's wholly representative of what's wrong with the music industry today.

Don't miss-understand me, I respect the artistry of the process they go through. They have all created a new personal piece. Respect for that part.

BUT, Music is more than re-sampling. The ORIGINAL artist matters. When I listen to music, I want to hear the artist who created the piece. I want to experience the sound of someone playing actual instruments. There is no replacement for the talent of a musician.

I would accept this IF the producer, actually crated their own samples first. This in affect is like a do-it-yourself paint-by-numbers kit.

I love the sounds, but I never want to hear music where it's so overly-produced that it erases or lays claim to a sound above the original musician's piece.

Where have all the musician's gone? - They all went digital! and the music died.

I work with Indigenous tribes & Indigenous activist groups throughout the west and midwest, everyday. They can be confrontational, no doubt. But, I also don't actually fault these brats. They just remind me of all of the jock ass ignorant privileged scum I grew up with in PA being confronted with something they aren't prepared for.

Not to mention the fact that we are now fully in a digital age of Google algorithms that basically give a person exactly what they are looking for and nothing else (an internet search used to be research in the 90's, siphoning through a lot of info). People are growing up in very insular bubbles; and ignorance breeds from that. One should also fault the educational system; but in a place like Kentucky, I'd imagine the social media bubble is fueling these kids' education more than their public schools are; there's always college (hopefully).

I'm pretty sure the vinyl itself has nothing on it. It's all digitized and stored in a module. The "Phase" device is just a very accurate, low-latency angular-position transducer for controlling the module.

So... why not just read the position directly from a special turntable (like the other digital sets they sell)? I dunno, I guess these let you use your favorite Technics turntables from 1989 that have just the right feel or whatever.

I don't know this, I'm just basing it on the evidence that there is clearly no stylus dragging across the record, so the sound can't be coming from there.

Ed: Oh, and I guess it's wireless. Maybe that's a big deal.

First off they use DVS technology which has been around and has nothing to do with what Phase is. I had no idea this was even a thing. https://en.wikipedia.org/wiki/Vinyl_emulation_software

https://www.digitaldjtips.com/2017/06/a-beginners-guide-to-digital-vinyl-systems/

With Phase you don't need the special time coded vinyl record or needles.

There may be a better explanation somewhere but that's what i got in 15 min using google.

I have questions.

Maybe I missed it, but I feel like they didn’t really explain what it is or how it works.

I guess it’s some kind of replacement for a record needle, that uses an accelerometer(?) or something, but I’d really like more details.

Also (and I know nothing about DJing, so tell me if I’m being an idiot), surely using this kind of digital wireless thing (again not sure how it works) would defeat the purpose of using analog vinyl in the first place?

The Zero's Chinese performance was ignored by the U.S. command prior to pearl harbor, dismissed as exaggeration. That's actually the crux of my point.

Exceptional moments do not change the rule.
Yes on occasion a wildcat would get swiss cheesed and not go down, but 99% of the time when swiss cheesed they went down.
Yes, there were wildcat aces that did fairly well (and Zero aces that did even better), but 99% of wildcat pilots were just trying to not get mauled.

Hellcat didn't enter combat till mid 1943, and it is the correction to the mistake. The F6F should have been the front line fighter at the start of the war... and could have been made sooner had Japanese tech not been ignored/dismissed as exaggeration.


Russian quantity as quality? At the start they were shot down at a higher ratio than the manufacturing counter ratio (by a lot). It was a white wash in favor of the Germans.
It took improvements in Russian tech to turn the tide in the air. Lend-lease only constituted about 10% of their air force at the peak. Russia had to improve their own forces, so they did. By the end, planes like the yak3 were par with the best.


The Mig31 is a slower Mig25 with a digital radar. Their version of the F14, not really ahead of the times, par maybe.

F15 is faster than either mig29 or Su27 (roughly Mig31 speed).
F16/F18, at altitude, are moderately slower, but a wash at sea level.

Why would they shoot and run?
We have awacs, we would know they are coming, so the only chance to shoot would be at max range. Max range shots are throw-away shots, they basically won't hit unless the target is unaware, which it won't be unaware because of the RWR. Just a slight turn and the missile can't follow after tens of miles of coasting and losing energy.


Chinese railgun is in sea trials, right now. Not some lab test. It wouldn't be on a ship without first having the gun proven, the mount proven, the fire control proven, stationary testing completed, etc.
2025 is the estimate for fleet wide usage.
Try finding a picture of a U.S. railgun aboard a U.S. ship.


Why would a laser rifle not work, when you can buy crap like this : https://www.youtube.com/watch?v=7baI2Nyi5rI
There's ones made in China, too : https://www.sanwulasers.com/customurl.aspx?type=Product&key=7wblue&shop=
That will light paper on fire ~instantly, and it's just a pitiful hand held laser pointer.
An actual weapon would be orders of magnitude stronger than a handheld toy.
It's an excellent covert operations weapon, silently blinding and starting fires form kilometers away.


Russia does not need to sink a U.S. carrier for no reason.
And the U.S. has no interest in giving Russia proper a need to defend from a U.S. carrier. For the very reasons you mentioned.


What Russia can do is proliferate such a missile, and effectively deprecate the U.S. carrier group as a military unit.

We need carriers to get our air force to wherever we need it to be.
If everyone had these missiles, we would have no way to deliver our air force by naval means.

Russia has land access to Europe, Asia, Africa. They can send planes to anywhere they need to go, from land bases. Russia doesn't /need/ a navy.

Most of the planet does not have a navy worth sinking. It's just us. This is the kind of weapon that disproportionately affects us.

"that doesn't justify using people in laboratory experiments"

uhhh, exactly how does holodoc think medical science works?
We use people in laboratory experiments all the damn time. It's called double-blind testing and it means that very sick people get given a placebo that we know does nothing.

I don't remember this episode, but I'm surprised at this lack of nuance from Star Trek.

And holo-space-nazi is right... it's funny how ethics go out the window when one of the main cast members life is threatened. But if a red-shirt is on the table....

Anyway, there's a massive difference between USING knowledge obtained by unethical means and GAINING knowledge by unethical means.

Don't get me wrong, medical ethics is really important. But throwing away knowledge after the fact is not only pointless, it's immoral. Especially in this case, where you're not even using the person who did the research, just a digital representation of them.

CDs were overpriced in my city, usually around $25. Until a new store opened, selling them for $13-15 then for 1 year everything tumbled down. It finally equalized out to under $20, right before the digital wave hit.

Shut up and take my money! Blu-ray and digital copy? Sure, I'm interested.

"Only 3% of people who use google have actually read the terms and conditions that they agreed to. "

3%?? I would have been amazed if it was as high as 0.3%.
3% would be (conservatively) over 10 million people. I doubt it's anywhere close to that.

I am not sure that privacy as a concept is even possible in a world with machine learning algorithms and big data. That's not a value judgment; I don't think privacy is worthless, I just find it increasingly untenable.

Machine learning has gotten so good, that even if you anonymise data, it's now pretty easy to tell a lot about you. Your digital fingerprint is there and an AI will be 99% correct about your age, gender, politics, sexual orientation, etc, even without you giving up that data.
