Making stars go supernova is a popular theme in science fiction. According to our current understanding of physics what would be the easiest (least completely impractical) way to artificially induce a supernova.

The short answer is we don't know.

Fibro is one of a number of disorders called functional disorders that are classified by their symptoms rather than their cause, because the cause isn't known or is disputed.

Other common function disorders you have probably heard of are chronic fatigue syndrome (aka ME) and irritable bowel syndrome. But there are loads others as well. Eg non epileptic seizures, tremors, blackouts, walking disorders, and some really weird stuff like not being able to move certain muscles.

Source I have a walking disorder, cfs and some fibro.

Cyber security has seen huge growth it the last 20 years. Machine learning is also huge. Data science is another field that has seen a lot of growth. Anyone these would be great or some combination of them.

Depending how old she is then i would focus on what she enjoys. If she is pushed into something that she doesn't enjoy or want to do that could put her off.

I will describe streaming encryption with AES because that's easiest. To be clear AES is not a secure hash function, it's a symmetrical encryption algorithm.

Just think of aes as a black box that does the following

• takes a key (128, 192, 256 bits long) basically a huge massive number. There are so many possible keys that all the computers in the world wouldn't be enough to try them all ... not even close.
• from this key the box outputs a key stream of one's and zeros that is different for each key.
• the key stream that comes out of the box appears completely random, has no structure and doesn't repeat.
• two key streams of two related keys are not related.

To encrypt your data, XOR* each bit of the data with each bit of the key steam. The the result is your encrypted data.

To decrypt the data you do exactly the same you did to encrypt, use the same key and your original data is recovered.

*XOR (exclusive OR) takes two binary inputs and returns 1 if the two inputs are different, it returns 0 if they are the same.
