India cuts the periodic table and evolution from schoolbooks – DW – 06/02/2023

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.
The first uses of the hypotenuse theorem came centuries before Pythagoras, unknown exactly when it came to be. Pythagoras just happens to be credited to be the first to document it.

The Pythagorean theorem is no foundation of anything. It is just one solution to one problem that nobody else had solved before.
Archimedes has built the foundations that you are talking about.
Just for clarification, so less people use it wrong:
a² + b² = c² (aa + bb = cc) is the Pythagorean Theorem.
a2 + b2 = c2 would be a+a + b+b = c+c.
That is taught in lower grades. The article is misleading. What is actually dropped is a specific advanced topic on the Pythagorean theorem.
Well it says mandatory, hopefully it still stays in most schools. Absolutely fucked tho
