How can the sum of angles of a triangle drawn on the surface of a sphere be not equal to 180 degrees ? I think he's wrong Edit: He's right! I just learned that it is possible for the sides of a triangle on a sphere at be at right angles. I have a hard time thinking about planes

Sir talking about non euclidean geometry really made my day!
It's spherical trigonometry made on sphere
Dr. H C Verma Sir ... Thankyou so much for making physics fun to learn. 🌹🫠☺️🙏💞💐
Sir ji you are great!
amazing teacher 😊👋
Sir ,Aap Globe ko Two Dimention kyon kah rahen hain?
pehle jab pata nahi thha ki earth flat h ki gol, tab 2-d geometry fail hote he pata lag gaya ki earth ka surface ek 3d surface h
Sir how I can join ?

Short distance kase straight line hoga , short distance is line segment between two points.
Visualisation power kam hai kya bhai
@SachinKumar-gz3ky Bhai you read properly. I think you don't read properly book. And you are not Msc In maths.

@@SachinKumar-gz3ky I know he Was prof of kanpur IIT, But you are not professor of IIT.
@@SachinKumar-gz3ky I think you don't know difference between line segment and straight line.

It is happening in spherical geometry.

Straight
Line ni hogi curve hongi to 180degree kese aayega
Matlab?

Lekin agar earth ke bahr se dekhe to curve wala path ayega kyoki earth flat nhi h
@@rockyhandsome1182 Bilkul sahi kaha aapne. A straight line is actually a curve. There is nothing really "straight" about a straight line
