@cwferrari it's indirect because they measured the particle's behavior, not its actual weight. it's still conclusive proof from a single experiment.

Honestly, these videos give you everything you need. The standard lessons run five or six times longer, and it’s easy to get bored or complacent. The shorter format delivers clear, strong explanations without wasting time, so you stay engaged and actually absorb the material.

I feel like calling these videos “Fast Track” doesn’t really do them justice. The name makes it sound gimmicky, like you’re taking a shortcut and won’t learn much from a 45 minute video. In reality, you walk away with a deep understanding. They move quickly, but they also feel more focused and more effective than the regular lesson library.

these fast track videos are slept on

Original Sentence: I would not be able to see Arun if he were in the next room.

Modified Sentence: If he were in the next room, then I would not be able to see Arun.

Sometimes you need to flip the order of the clauses in a conditional sentence. Think of IF → THEN like a math equation. The sentence has two parts: X and Y.

X is the condition, so it always goes in the “if” part of the sentence.

In this example, “if he were in the next room” is X. Since X is the “if” part, you put it first.
