Every PhD student's journey is unique, just like the problems they are working on. It is important not to lose confidence by comparing yourself to others. As long as you love science, the journey will always be pleasant.

@DSathNat Funny how TVK supporters ignore Ambedkar & other intellectuals when asked to explain the rationale behind voting for Vijay. When the majority of people vote for charisma rather than governance/policy, it becomes essential to question the strength & legitimacy of that mandate.
@kittushanks And choosing leaders mainly for charisma is often what creates parties that end up bribing voters in the first place. It’s a vicious cycle. If politics stands on ideology rather than idols, people probably won’t expect money for their votes either.
@DSathNat Democracy has always been crazy, as it allows people to choose their leader from films. Vijay won this election largely through his fame & glamour, and his victory has little to do with the voice/struggles of the common people. Here is what Dr. Ambedkar says about hero worship:

Travelling in Train no. 13247. The AC is not working and the charging ports are also non-functional in my coach. Passengers are facing difficulty. Kindly rectify the issue at the earliest.
Here, the parameter h controls how far a trial trajectory deviates from the exact one. The exact trajectory according to the Schrodinger equation makes the action stationary (a maximum in this case).(8/8)
The stationary action principle is not limited to classical physics - like predicting the path of a ball in free fall.
It also determines the evolution of quantum systems in a way analogous to classical trajectories. (1/n)
The stationary action principle states tht among various curves between two points in position-time graph, the ball chooses the path for which 'Action' is minimum n that path turns out to be parabolic. So inorder to keep the action minimum, the ball takes a parabolic path (5/n)
The video below shows different scenarios of wavepacket evolution for a given initial and final widths.
The dotted one is the exact evolution given by the Schrödinger equation.
The others are artificially modified.(7/n)
