Jean-Baptiste Biot was born on April 21, 1774. A French physicist, astronomer, and mathematician who co-discovered the Biot–Savart law of magnetostatics with Félix Savart. He established the reality of meteorites, made an early balloon flight, and studied the polarization of light. The biot (a CGS unit of electrical current), the mineral biotite, and Cape Biot in eastern Greenland were named in his honor.

I came up with a very good meme (I think it was very good anyway) last night but now I’ve forgotten it

Well- fine I guess. At least I didn’t forget Biot Savart’s law

[just-another-bored-killjoy]

trying to study from physics wallah is so embarrassing. like im trying to understand the derivation of biot savart's law and every 15 seconds he goes KHACHAAAAK KHAACHAAAKK MMMMM KHACHAK

Huh... but it is essentially a "history is written by the victors" situation. It's not that Europe stole or conquered mathematics from India; it's that the narratives that were constructed around the development of math and science centuries later almost exclusively center European contributions rather than contributions from other places and people (at least in the US - can't speak for other places).

To be clear, my experience is the history that is taught to physicists of our field at the college level. There are probably academic historians out there doing great work, but the average expert in the field of Physics in the US is not going to know anything about any of that. In our physics textbooks and classes, we learn about a handful of Greek scientists of Aristotle's time, and then skip ahead to the 1500's or 1600's in Western Europe as if nothing happened in between. It's not even just that books leave things out - they also include outright misinformation. I've had to request revisions to multiple college textbooks for making egregiously incorrect claims like "Aristotle's view of scientific methodology was entirely unquestioned until Galileo." This is the education that college-level physics students are getting about the history of their field!

I spend a little time at the start of my college Physics lectures informing students a about some of the lineage behind our most fundamental principles, including contributions from communities of scholars in India, Alexandria, around the Islamic Empire, etc, and they are always flabbergasted. In my years of teaching college students, basically none of them have ever heard anything about any of this. Instead, they've heard things like "Newton invented Calculus" (AAAUUGHH! NO!!!!).

Now, I don't think there's some overt, sinister plot on the part of textbook authors to erase people of color. This is just a part of the fabric of colonialism: over the course of hundreds of years, certain narratives are assumed to be more worth telling and preserving, certain languages are more commonly translated and recorded in the standard literature, certain information is more accessible, certain names are considered easier to spell and pronounce and therefore more likely to be assigned to laws, etc etc. Most modern people are just working with what they know. But that doesn't change the fact that this is absolutely a product of colonialism and privileging European narratives and contributions over others for the past several hundred years. It's just bonkers that every US-educated physicist can name Newton, Galileo, Boltzmann, Kepler, Pascal, Archimedes, Kirchoff, Ampere, Bernoulli, Faraday, Maxwell, Gauss, Biot-Savart (though they generally pronounce it wrong), and a few dozen more European names by the laws and theorems named after them and yet most probably don't know the name of a single Islamic scholar. That is absolutely a by-product of colonialism - I'm kind of confused that you seem to be suggesting that it's not, unless I'm misunderstanding.

Biot–Savart Law

Introduction The Biot–Savart Law is a fundamental principle in electromagnetism that describes the magnetic field generated by an electric current. Named after physicists Jean-Baptiste Biot and Félix Savart, the law provides a mathematical description of the magnetic field in terms of the current source that produces it. Statement of the Biot–Savart Law The Biot–Savart Law is typically…

[definitelynotnia]

don't be overwhelmed, ik im asking you to do a lot of stuff and ofc its not possible to do all of this for all 14 chapters but listen do as much as you can, even if it gets you 2-3 marks extra it'll be worth it, here's a few places you can start from:

oneshot videos of Dual Nature of Radiation and Matter, Atoms and Nuclei they're all heavily formula based and the questions are mostly directly formula based so watch the really really short ones with just derivations and formulas while making notes

Ray Optics diagrams, we've done these before so it'll be easy and a lot of questions tend to come from this chapter

Current Electricity questions on circuits, basically Equivalent Resistance and Kirchoff Laws, even meter bridge and wheatstone bridge are super easy formulas and derivations and that has a good chance of coming

Derivation of Ammeter/Voltmeter from Galvanometer, Derivation of Electric Field due to Dipole (Axial and Equatorial) as well as Potential due to Dipole (its the same method so easy to remember)

Biot-Savart's Law, LR/LC/LCR circuits from Alternating Current once you do one circuit its easy to remember them all and questions from phase difference will definitely come

i hope you manage to do at least some of these and you'll definitely pass don't worry about it, sending good vibes and a hug <3

Can I pass physics just from theory? Idk derivations or how to solve numericals....

Cbse class 12 2024

♣

look you need 23-24 marks to pass, and if you did good in practicals just passing theory could pull you into the 50s

so to answer your question, yes you can probably pass with just theory provided you can solve at least some of the MCQs which are directly formula based, Assertion Reason questions, the case-based questions which are theoretical and at least 10-12 marks in general will definitely be theory so adding up all that you could probably manage to pass

however if you're planning on giving entrances most cut offs are 60% in science subjects for eligibility and you still have a day so I would suggest going through the derivations and learning as many formulas as you can

just knowing some formulas will really help in MCQs and in numericals even if you cannot solve them just writing the formulas and putting the values will fetch you marks cz of step-marking so try and learn as many formulas as you can, and derivations will help you with not only knowing the formulas but also get you 3-4 marks per question so I suggest you start with that

here, use this

also, go through the graphs, at least 1-2 questions will definitely come either based on graphs or based on "if X increases Y will increase/decrease/remain constant" so knowing a few graphs might be useful
