Last year, I took a number of vacations which involved cruising, diving, snorkelling and walking on glaciers. Thinking back on those trips, I could not help but notice that water and ice exhibited different colours in different settings. I decided to dive deeper into the colours of water. Finally, here are my findings. Water’s True Colour The colour of an object mainly depends on the colour of light emitted from it. In the case of water its colour is also affected by factors like light source, absorption, scattering, and suspended materials. Absorption by water is stronger for red light, but weaker for blue light. Water is therefore, intrinsically blue. However, this effect is only apparent when the water is reasonably deep. This is why a glass of water appears colourless whereas a big aquarium looks bluish through the thickness of water. Why is the Sea Blue? I did two cruises last year, one in the Caribbean and the other in the South Pacific. Owing to the depth of the wate...
Towards the end of 2024, I left the 9 to 5 routine given my financial goals were achieved. It felt great not needing to hug my phone to sleep and being able to wake up at whatever godly (or ungodly) hour desired. Fast forward six months, the retirement routine became mundane. I needed to find meaningful use of my newly found time. Between street and league soccer, writing a book, exotic getaways, relocation back to my adopted home country, all the while taking on advisory gigs with interesting companies, life seemed like a handful. Somehow, I managed to find time to study various topics of interest. One topic that really caught on was game theory. Learning game theory was a self-improvement initiative. I wanted a life broader horizon and be better equipped when when dealing with others. My definition of game theory is the study of interactive decision making of more than one party, where the outcome of each particpant or player...
Want to make $250 000 ? Find a big prime number, a really big one. It turns out there are organizations ready to dough out good cash for a really large prime number. This is because primes are used in RSA cryptography . RSA Algorithm Let's look at the algorithm: 1. Multiply two large prime numbers p and q to get the product N 2. Find two numbers e and d , such that ed = 1mod((p-1)(q-1)) , where e and N are relatively prime meaning they do not share any prime factors. 3. Let's call M the original message and C the ciphered message: a. To encrypt: C = M e mod(N) b. To decipher: M = C d mod(N) In essence, using the public key ( N,e) will...
