We tried a plastic-free week at school. We mostly failed, and that was the whole point.
A tally sheet, a mountain of wrappers, and what I learned about the difference between my choices and the system.

Colour theory for notes: why my rainbow pages stopped working and what fixed them
A notes queen's confession. More colours does not mean better notes. Here is the actual design logic.

NDA, CDS, TES: which defence entry is for a PCM student from a small town, and what does the life look like?
I'm in class 12, PCM, in Patna. Honestly, I'm not sure about engineering colleges because of money, and I've always liked the idea of the armed forces: the uniform, the discipline, and a steady life. My uncle's friend wa

Is displacement current real? Do charges cross a capacitor gap? Showing I_d = I for a charging capacitor
I have been staring at the Ampere–Maxwell law for two days. A capacitor is being charged by a current I in the wire. I draw a loop around the wire. If I choose a flat surface bounded by the loop that the wire passes thro

Why E = σ/2ε₀ for an infinite sheet but σ/ε₀ just outside a conductor? Same Gauss law, different answer
Doing the Gauss law applications for boards + NEET and I've hit something that feels inconsistent. For an infinite plane sheet of charge with surface density \sigma , I use a pillbox through the sheet and get 2EA = \sigm

Habitat vs niche: if many species share a habitat, how can each have a different niche?
I like ecology because it reads like prose, but the habitat vs niche part reads like a riddle. NCERT says the place where an organism lives is its habitat, and that a habitat has many niches. The niche is the functional

Unaffected parents but affected son in a pedigree, autosomal recessive or X-linked recessive? How do you decide?
Pedigree analysis is eating my marks in mock tests. The usual one: two unaffected parents, a shaded affected son, and the other kids a daughter and a son unshaded. The question wants "mode of inheritance". I know both au

Sperm vs ovum structure: is it ovum or secondary oocyte that is released at ovulation, and what do the layers do?
I am making a super neat comparison table colours, arrows, stickers, all that! for sperm and ovum, but I got stuck on two rows and I hate leaving blanks! Sperm: head haploid nucleus + acrosome , neck, middle piece mitoch

Carnatic vs Hindustani: a biased but fair guide for the curious
I learn Carnatic vocal, my neighbour's cousin learns Hindustani, and we have been "debating" for two years. Here is what I wish someone had explained to me earlier.

AC generator doubts: what changes if speed doubles, and where does the electrical energy actually come from?
Boards + NEET so I need this clean. NCERT gives e = NBA\omega\sin\omega t for a coil of N turns, area A, rotating at angular speed ω in a field B. I did a numerical: coil 50 turns, area 0.02 m², B = 0.4 T, rotating at 30
