Prof. Balakrishnan was my physics professor at IIT Madras when I was there getting my engineering degree in the early 80s. Brilliant professor, humble person. I even took a Quantum Mechanics course with him in addition to the engineering physics courses that all undergradsd had to take. I can still remember everything he taught.

These lectures are fantastic. The bit on heat and reversibility is particularly interesting. It seems that there lies a connection to the ubiquity of "workless" constraints. One thing I don't completely agree with is that I feel that Newton's formulation handles constraints just as well as Lagrange's once you introduce the concept of virtual work and d'Alembert's principle. The workless constraints disappear from the EOMs just like they do in the Lagrangian.

It is not correct to imply that Newton’s laws are somehow equivalent to the Lagrangian method. The latter is only when you know the generalized coordinates that respect constraints. Newton’s laws are more general. Lagrangians have to be derived from Newton’s laws for holonomic constraints.

At 15:10, I don't understand why the thing inside the curly brackets should be 0. Since delta q is arbitrary, he says, he makes the thing inside curly brackets 0. What if it (the thing inside curly brackets) is some sinusoidal function (or any odd function) integrated over it's time period, giving 0 as an answer?

Delq is not 0 at all point of phase space trajectory and we see that left hand side is 0 so it implies that of delq is not 0 then the quantity inside curly bracket must be zero since delq is 0 only at t1 and t2

The us treasry came back their highest intrest in over a year as b tc dropped although it did plug the week's lows at nearer 53K, the latest dip to 54k highlights it’s correction after hitting all time highs of 6Ik.The dip came in tandem with gain in treasry b ones however, while fundng rates also cooled bullish sentiment g ained beyond spot price action. Long term bond warning compounds the topic of instittional invovement bringing significant announcements from prospective large volume crporate invstors and removed any doubt that the instittional scene will transform. I knw starting nxt week, we’re going to see an absolute drumbat of pretty game changng milestone from some of this firms that are relly going to mark the new point in b tc adoption and availability, products and services within the existing traditional finane landscapes so the topic of b onds has g ained attenton. invstors should stay away from dolar denminated tagets as peple are incresingly intrested in buying b tc as a hedge against cntrl bank & infinite money prnting, while at the same time, supply is exiting the market. just in case anyone is wondring if am still bullish I gt my 31 b tc at 55k hodl I gaind thru Mr wellington analyst & as usual he believes we don’t need charts to tell us that b tc will continue to rise and rise in the foreseable future. if you are on T...E..L...E...G....R....A...M you can easily reach Mr. Wellington @wellingtontrades
