Oohh yes. That's it. And the only complete explanation was done using quantum physics (and not restricted relativity) and particle statistics

An ideal Maxwell-Boltzmann gas

hmmmm. Impressive
On which u can apply either maxwell-boltzman or bose-einstein statistics (in this case u consider the quantum nature of particles).

The Sackur-Tetrode equation

OK. Thermodynamics isn't my favourite subject

As everyone knows, knights tell the truth all the time, and liars lie all the time. At least, this is what evenly behaved knights and liars do.
Less known is that there are also odd knights, who on odd-numbered days lie all the time. (On even-numbered days, however, they behave evenly, and tell the truth.) Also, there are odd liars, who on odd-numbered days, tell the truth about everything, while they lie the rest of the days.

Someone said: "Today's the 3rd. Trust me, I'm telling the truth. I'm odd. I didn't lie yesterday. I'm not a knight."

At first, this seemed illogical, and I thought he couldn't be either a knight or a liar, even or odd, but after a while the solution dawned on me and I found the error in my reasoning. What is he?

mmm...maybe I've missed something, but why can't he be an odd liar?

"Today's the 3rd. Trust me, I'm telling the truth. I'm odd. I didn't lie yesterday. I'm not a knight."

An odd liar would be telling the truth on the 3rd but lying on the 2nd.

mmm...on second thoughts cara rivale, why are we putting restrictions to ourselves which are not there?


Possibility...?

Perhaps he didn't say a word on the 2nd! So effectively he didn't lie!


How about geographical positioning?

On the 1st, the odd liar was on the east side of longitude 180 for the whole day, then switched to the west side of longitude 180 the next day which would have been the 3rd!

You have to sort five weights weighing 51g, 52g, 53g, 54g, and 55g. You have a balance scale with which you can compare the weights. But after solving so many sorting puzzles, it is starting to break down.
If the difference between two weights is greater than 1.5g, the scale will correctly determine which side is heavier. If the difference between the weights is less than 1.5g or equal, the scale will indicate the weights are equal.

Sort the weights in the smallest number of weighings.

I can't type a full answer here, too tedious.

Is it 7 weighings?
