We will be featuring different members of the Brilliant community, so that you can get to know them better. For the first issue, we are featuring Jake Lai.

Jake created the problem In the land of 13 dimensions, which is based on an identity that jake found as he was playing with the roots of unity. He promises to write a wiki on it soon!

What is \(\sum_{k=0}^{\infty} \left[ \frac{1}{(13k)!} - \frac{1}{13(k!)} \right]\)?

In the solution to Fibonacci is fun, Jake shows us how to calculate \(\sum_{n=0}^{\infty} \frac{F_{n}}{3^{n}}\) using generating functions

**1) Tell us more about yourself.**

I'm Jake, a half-Thai half-Singaporean! Shout-out to all the Singaporean/Thai users!

My real name is Lairoongroj Jinnawat, but my friends find it hard to pronounce; hence, Jake Lai. My interests include piano (mostly improvisation), anime, poetry/creative writing, drawing, listening to music and staying up late. Most importantly, I love messing around in the realms of mathematics and physics (of course) and making music of all kinds.

\[\]

**2) What is one fun fact about yourself that the Brilliant community doesn’t know about.**

I actually despised maths in primary school. I couldn't understand what people could possibly feel so passionate about. To me, maths was just tedious: counting, multiplying, memorizing formulas. I didn't "get" it.

However, by March 2013, I was getting into quantum mechanics (sad to say through YouTube quantum woo) and realized QM was really heavy on maths. I let go of my preconceptions of maths and started relearning algebra, getting into its essence.

Soon after, I bought a triad of O-level textbooks, which broadened my scope of maths; I roughly knew what it was now: even more than mere symbols to manipulate, rearrange, it was deeply connected with the universe, a language. Yet, it was the search of beauty: in symmetry, in structures arising from fundamental axioms. So here I am now, and here I venture forth.

Oh yeah, and I can't whistle. But I can beatbox!

\[\]

**3) What do you want to accomplish in the next few years?**

I don't have short-term goals, only long-term goals. The future is uncertain as of now.

It would be great if I could become a theoretical physicist though.

Physics has always intrigued me because I've always been naturally curious, even when I was very young. I wanted to know how things worked; not as an engineer would, but rather on a deeper level. I was fascinated by how, fundamentally, the universe appears to be probabilistic, and how these quirky microscopic phenomena could give rise to the macroscopic world we're so familiar with. I was also interested in relativistic effects that appear when you travels at speeds close to \(c\); who would ever imagine that, just by moving quickly enough, you could experience space and time entirely different from other observers!

I'm trying to master classical mechanics at the moment. I'm quite fond of EM too, as well as QED/QCD. I'm interested the mathematics of fluid dynamics but so far it has yet to fully capture my attention. I'm also reading up a bit on tensor calculus, which is essential for relativity. M-theory is also something that excites me

\[\]
**4) What do you wish for Brilliant?**

I wish for Brilliant to be more popular and more diverse. Tell your friends, tell your family! Tell them, "Don't be scared of maths/physics, it won't bite! Probably!" Brilliant has a bright future ahead. Here's a (futile) wish for myself, too: I wish I'd joined earlier. Oh well.

"The universe appears to be probabilistic". Well, yes, I'm very fond of that paradigm, i.e., perhaps maximum entropy production is what's behind many if not most of the laws of physics.

I share with you your hopes for Brilliant.org. Congratulations for being the first featured member. Hang around! – Michael Mendrin · 2 years, 3 months ago

There really is no right way to study up on maths; you have to find your own comfortable spot: is it focused on textbooks, exercises, quizzes, or just surfing the web? Explore these options, and see which combinations work best! – Jake Lai · 2 years, 3 months ago

Well, thanks for replying. I agree with you that there is no right way to study up on maths but not only maths, there is no right way to study any subject whatsoever. BTW, what does your status mean?Log in to reply

Jake, half-Singaporean? I am your neighbor, a Malaysian. And in Malaysia, race or ethnicity is a big thing. It decides if you get special privileges from the dysfunctional government. Anyway, back to Singaporean. Genetically, what is a Singaporean? Isn't it a nationality? So you mom is a Chinese or Chines-Indian? Your questions are tough can't solve many of them. – Chew-Seong Cheong · 2 years, 3 months ago

I hold both passports; Singaporean is definitely not an ethnicity, but nationality, rather. My parents are both Chinese.

Feel free to contact me via email/Facebook if you would like some hints! Nice to hear from you! – Jake Lai · 2 years, 3 months ago

That's a pretty organized study table. I always mess up mine .

For the fibonacci question, is there another solution, really?

Congrats btw, @Jake Lai – Agnishom Chattopadhyay · 2 years, 3 months ago

Thank you! I'm sure there are more than three approaches, so I'll try to think of one more; you should try, too.Log in to reply

What are some great tips on learning music? – Agnishom Chattopadhyay · 2 years, 3 months ago

Log in to reply

– Jake Lai · 2 years, 2 months ago

Get a good feel for the types of music you like. Listen to lots of music, even stuff you wouldn't normally like. Pay close attention to elements of music in everyday life. Experiment :3Log in to reply

@Jake Lai Sorry , if you took wrong meaning of our chat. I think you misunderstood me. Sorry if you felt angry because of my words , because I didn't know you well . @Julian Poon has explained me everything.I only had intention to be a good friend of you. – Nihar Mahajan · 2 years, 3 months ago
