Actually 128 int uses 2 times the storage for less dynamic range. I agree however that for financial applications int is always better. You don't want float dynamic range on finance calculations

Totally expected. No business model at all. Miracle it worked for so many years.

while they do have therapeutic effects (some, I wouldn't say alcohol does), I don't think they should be proposed as methods to relax stress. Too many downsides and are not sustainable as regularly used substances. Yes you do feel great in a night of MDMA but the feelings you have the following days almost negate the positive aspects.

If your only interaction was "follow instructions and build one in the lab", doesn't that tell you exactly there is something deep you didn't understand at all?

I do not know or care what would Mr. Shannon think. What I do know is that the base you chose for the logarithm on the entropy equation has nothing to do with the amount of bits you assign to a word on a digital architecture :)

That is a bit in information theory. It has nothing to do with the computer/digital engineering term being discussed here.

100%. Every time I read the term "antenna" when referring to the coil used for NFC/RFID I suffer inside...

> the geometrical interpretation of an outwardly expanding spherical shell of power shouldn't depend on frequency

I think nobody says that is does. I believe the problem is to call Friis transmission equation "Free-space loss". Actually the Friis formula is composed of 3 terms: the receiving and transmitting antennas gain and the actual free space loss which has the 1/R^2 dependency (which actually isn't a "loss" in energy balance terms, since it's not lost energy, just energy not received at a certain point, so we could argue about that term too...)

How can an equation that does not represent a balance of energy violate energy conservation?

With path loss equation I assume you refer to Friis equation which is just the ratio of power received at an antenna to power given to the transmitter. It is correct and does not violate conservation of energy since it says nothing about the power not received at the receiver

>Money is created when debt is issued and it is destroyed as the debts are repaid

I understand money is created with issued debt, since the interests do not exist yet.

I don't understand why do you say money is destroyed when interest are repaid? If the bank now holds that money, why do you say it is destroyed?
