"Alternative Math" - The confusing times we live in
Har har har.
I went through every calculus class my uni offered, so not so much.
Mayhaps I didn't explain the example given in enough length. The simple operations of addition, subtraction, multiplication, division all have a single correct answer. Insisting that students find multiple methods of performing those operations and demonstrate multiple different learning methods for them is mental masturbation. You could spend that same time actually moving on to the more advanced stuff that is supposed to 'in theory' prepare them for.
Another example was solving a double digit multiplication problem like 37*86. The marking example showed a student using the old school vertical method and showing their work to arrive at the correct answer. The provincial grading system declared that as WRONG. The student was 'falling back' on the algorithm and should have demonstrated the use of multiple methods of solving the problem. That is idiocy.
Basic add/subtract/multiply/division isn't MATH it's arithmetic and it's a basic operation with a single answer and so long as you use a correct method to arrive at the correct answer you are good to go. Teach students that foundation and then move on to teaching them actual MATH. Read through our provincial curriculum, they are STILL teaching add/subtract/multiply/division at the Grade 11 level in the curriculum on the premise that students are still 'mastering' something that should've been a given by junior high.
What you describe is called a "proof" (a pretty simplistic one). It is not a new concept, it's an integral part of doing math. I learned that in the early 80's, right before trig/pre calculus.
Maybe it just seems insane because it's more advanced than your last math class? It's absolutely not institutionalized stupidity....it's standard math.
Near Miss
OK, a few things.
60 km/h is about 37 mph and although I don't know the exact speed limit on that street, it's not unreasonable to assume it's 50 or 60 km/h.
In the video, the light turns yellow approximately 1.5 seconds before he enters the intersection. He is going 54 km/h at that time. This means he is approximately 23 m from the intersection when the light turns yellow.
According to nacta.org, the safe stopping distance for an average driver at 35 mph is 136 ft or around 41 m.
From the Ontario Highway Traffic Act: Every driver approaching a traffic control signal showing a circular amber indication and facing the indication shall stop his or her vehicle if he or she can do so safely, otherwise he or she may proceed with caution. R.S.O. 1990, c. H.8, s. 144 (15).
Also from the Ontario Highway Act: No driver or operator of a vehicle in an intersection shall turn left across the path of a vehicle approaching from the opposite direction unless he or she has afforded a reasonable opportunity to the driver or operator of the approaching vehicle to avoid a collision. R.S.O. 1990, c. H.8, s. 141 (5).
Or when you're on a motorcycle actually follow the rules of the damn road?
Yellow means stop if it's safe. He had tons of room to stop and decided to hit the gas instead. LOS doesn't matter, he was the one breaking the law, yellow light is the left turner's chance to turn.
Guy was being a prick and then complains about the other guy's driving.
There's a reason the majority of organ donations come from motorcyclists.
Also, missed this the first time round. He's in an urban area doing 60. So on top of running the light, he's speeding!
Movie Accent Expert Breaks Down 31 Actors Idiolects
Favorite part is the contrast between 11:37 John Wayne as Genghis Khan and 11:44 Meryl Streep as Julia Child. Awesome.
Inside the mind of white America
I checked...you're right.
Survey respondents were asked about unfair treatment of blacks in seven specific institutions or realms of community life: the police, the court system, the workplace, stores and restaurants, public schools, the health care system and elections.
49% of whites answered there was none in any of those categories.
What's worse is, when taken individually, it averages out to only 20% of whites think blacks are treated more poorly than whites in those categories. (37% say cops are biased, 13% say voting is).
I'm astonished at those numbers, even if they're 4 years old.
I assume it's in reference to the Pew Research Centers study mentioned in the video description.

Atheist Angers Christians With Bible Verse
You might want to re-read your bible (I refuse to capitalize it).
Revelation 19:6:
And I heard as it were the voice of a great multitude, and as the voice of many waters, and as the voice of mighty thunderings, saying, Alleluia: for the Lord God omnipotent reigneth.
Also Matthew 19:26 “with God, all things are possible” and Luke 1:37 “with God nothing is impossible” make it clear the Christian god is omnipotent without actually using the word.
And even if it wasn't explicitly written, in practice every major sect of Christianity follows the doctrine that the Christian god is both omniscient (i.e. going to judge everyone for their sins on judgement day) and omnipotent (i.e. can do anything, such as create a universe from nothing).
EDIT: So @newtboy's original comment stands. The bible's inconsistencies are too huge for anyone not completely indoctrinated into Christianity to ignore.
Simple question:
Where in the bible does it say God is omnipotent?
I ask because as far as I know it doesn't. It speaks of his power, mystery, understanding all being great. But it doesn't say he is omnipotent. The closest you'll probably get is in Jeremiah where he has a high opinion of God saying "nothing is too hard for you".
The Dolly Zoom: More Than A Cheap Trick
This is not necessarily on topic, but good grief i never realised pictures of someone's face could look so different. The bit at 1:37 with the woman's face was a revelation! I didn't know that happened, and it kind of explains some pictures i've accidentally taken with forward facing cameras (and been horrified by). I always thought i must have good/bad days and look terrible sometimes, but that explains a lot.
In Thailand i had a picture taken on a tree-platform-zipline 80 feet in the air, sweaty, red, disheveled and sleepless... and it's the best picture i've ever seen of me, and my skin looked uniform and nice, not red and damp as it did in a mirror there. Sorry for off-topic, but how the feck does that work? It wasn't airbrushed or anything, they had very little time for processing. I feel like 50% of my mystery has been answered in that one moment of the video!
John Oliver on Bill O'Reilly etc
I thought we aren't supposed to post full episodes (37.4). This can't be public domain already, can it? It aired last night.

Abba - The Last Video
Who's in the mirror at 4:37? Is that Eddie from Iron Maiden?
