Every time I solve a Doppler question I do 50% by guess on the signs. In my head I have: f' = f\,\frac{v \pm v o}{v \mp v s} and I don't have a rule for which one is plus. The textbook example I tried: a source of freque
One camp says cram everything, another says stop and relax. A plan that revises selectively and rests deliberately.
It's 3 am again and the anxiety is doing its thing, so I'm doing chemistry instead of staring at the ceiling. Group 13 data from NCERT. First ionisation enthalpy kJ/mol : B 801, Al 577, Ga 579, In 558, Tl 589. I expected
Colour-coded notes for factors affecting photosynthesis: light yellow , CO₂ grey , temperature red , water blue , and I thought I was done. Then I did a graph-based question. The graph showed photosynthetic rate vs light

Gattermann or Gattermann-Koch? Rosenmund or Stephen? A system for named reactions that survives revision.
Planner update: the "gene transfer" page has been sitting in red in my tracker for three days. I'd like it to turn green 😅 From NCERT: DNA is a hydrophilic molecule, so it can't pass through cell membranes. To make bacte
