In a statement, the council rationalized the reduction by stating they wanted to reduce the content load on students in light of the Covid-19 pandemic. On June 1, India cut a slew of foundational topics from tenth grade textbooks, including the periodic table of elements, Darwin’s theory of evolution, the Pythagorean theorem, sources of energy, sustainable management of natural resources and contribution of agriculture to the national economy, among others. These changes effectively block a major swath of Indian students from exposure to evolution through textbooks, because tenth grade is the last year mandatory science classes are offered in Indian schools.
And just like that, 1 in every seven kids in the world got royally fucked.
Right?
Let’s see, Pythagorean theorem, is what, a couple thousand years old, and a single statement, right? And it’s the foundation of geometry and trig. Hell, I regularly say it in my head (a2+b2=c2) when trying to figure out spatial relationships, for dumb stuff no less (will this table fit on my patio with room to walk around it?).
It’s how you ensure anything you’re trying to make square is square. In framing (shed, house, deck, whatever) it’s used to ensure you setup your string in the proper orientation and don’t end up with a parallelogram.
And the Periodic table… The bloody basis of understanding chemical reactions and physics.
I guess if you’re not teaching the Periodic Table, there’d be no hope if understanding evolutionary theory, since it’s predicated on chemical behaviour.
Seriously… the Pythagorean Theorem is the single most important piece of practical math that can be easily taught to everyone.
And I just recently used it to measure the length of christmas lights I need for my roof, being 15 years out of school.
I’m a software engineer and I think one of my personal favorite random applications of Pythagoras/ trig was in my data visualization class back in scool. The assignment was to take a dataset of Soviet space launches with dogs and display it in an interactive approachable manner (ie less rigorous data science and more local science center), so I thought it would be fun to show rockets for each lauch and animate them rotating around the earth. Queue the trig to place each icon an appropriate distance (scaled to the launch height in my data), angle, and spacing from the earth.
I’ll admit it doesn’t come up all that often (in web development), but it’s nice to have that foundational knowledge to dredge up when I need it.
That is taught in lower grades. The article is misleading. What is actually dropped is a specific advanced topic on the Pythagorean theorem.
Just for clarification, so less people use it wrong:
a² + b² = c² (a*a + b*b = c*c) is the Pythagorean Theorem.
a2 + b2 = c2 would be a+a + b+b = c+c.
when i’m away from my computer’s compose key, i put the exponent after a term to do it in plain text, and would write the latter as 2a+2b=2c.
Well it says mandatory, hopefully it still stays in most schools. Absolutely fucked tho
