1) If you want to get a job done efficiently with computers, the first question is: "What is the job?". It is not which computer language, technique, or fad of the year to use. A specialist in the application has a real advantage over a specialist in computer science. Of course, both are...

For one thing, if the sum of the angles of a triangle are not 180 deg., then there is curvature.

Yes, in this case. This case has a very short message where it is hard to know when a decrypted result is a valid phone number. (But decrypting to a valid local area code might give a clue.) Given a longer text message, it might not take long to decrypt it by brute force.

The main difference is that your example uses a symmetric key, "your birthday MM/DD/YYY", known by both parties, to both encrypt and decrypt the message ("my phone number"). A public/private key system uses asymmetric keys, one to encrypt and another to decrypt. The person who owns the...

That certainly is one application. It uses the public/private keys to allow a person in the public who receives a message that you send to know the authorship because he can decrypt it. It does not protect your message from being read by others. Another application is what I tried to describe...

My (non-expert) two cents: Suppose I broadcast a "public key": aieo19gkeu, and say that anyone can use it to encrypt and send me a message that nobody, except myself, can decrypt. ADDED: aieo19gkeu can not be used to decrypt a message that it encrypted. I am the only one who knows the private...

The only exception I can think of is if AI tools are provided by a company that makes some guarantees of the results. Then they would take on some legal risk.

I would say this a little differently: There are things (like crystal structure) that are natural to represent using a non-orthogonal basis. For the actual mathematical calculation, transforming to an orthogonal basis can make the calculation easier. Then the solution can be transformed back to...

Unless two variables, X and Y, are not related, they will not be orthogonal. The vast majority of variables related to the same subject of interest will also be somewhat related to each other. More often than not, two variables must be analyzed if one wants to determine components that are not...

Would you say it is "possible" even if the probability of it happening in the past life of the universe is minuscule?

I don't know how much complex analysis you have had. If you just want to multiply by something to make the denominator real, notice that: ##(1+z)(1+\bar{z}) = 1+\bar{z}+z+z\bar{z} = 1+2Re(z)+|z|^2##, which is real for any complex number, ##z##.

So "Office Space" was fiction??!? It sure seemed realistic to me. :-) (Don't it feel good to be a gangster?)

In every subject, at every level, the curriculum is designed to cover what is needed to succeed at the next level.

You can look to see if outliers are present in the winning teams.

Ha! If anything identifies you as a hard-core purist, that statement does! I'll be interested in how that goes. :smile:
