Math is awesome.

It is beautiful in its own right and a way by which we can understand the world.

That being said, those who bravely pursue fields that heavily use mathematics may sometimes feel like they want to rip their hair out.

To help ease the pain, Business Insider put together a list of small gifts and gadgets that math lovers might appreciate.

So if you know someone who has a probability final coming up, or spends nearly a hundred hours a week working on excel sheets, here are some things you can get them this holiday season.

A nifty bottle opener for the poor souls pursuing their PhDs

If you're a fan of the Möbius strip, say hello to the Klein bottle. To put it simply, it's a closed surface with only one side and is formed by passing one end of a tube through the side and then joining at the end. It doesn't have an inside or an outside.

But it's also a cool way to open your beers.

And if you'd like something a bit more classic, you can also get yourself a π bottle opener.

A book or two to sharpen your chess skills

"My 60 Memorable Games" is a masterpiece. It's one of the most important chess books, written by one of the game's greatest legends, Bobby Fischer. If you're a serious chess player, you need to have it.

Plus, if you are rated under 2000, we recommend looking at Ludek Pachman's "Modern Chess Strategy," a concise and highly readable text.

A mini attachable "telescope" for your iPhone

This mini "telescope" camera attaches to your iPhone and comes with 18x magnification and a tripod.

It's a fun, astrophysics-ish gadget, and is easier to lug around that a professional camera.

A cool alternative to the varsity jacket

This baseball cap makes for a great stocking stuffer.

Plus, it subtly references the publication of Isaac Newton's "Principia," one of the most game-changing texts ever published, and covers the fundamental three laws of motion, the law of universal gravity, and more.

This crystal-growing project makes a great gift for young math lovers.

If there's a young science enthusiast in your life, this crystal-growing kit will make for a great gift. It's a fun way to get out of the textbooks and into real-life experiments.

We apologize in advance for any major messes you will have to clean up.

A science-y version of the classic whiskey book

"Proof: The Science of Booze" traces through the physics, biology, chemistry, neurobiology and more behind one of humanity's greatest past times: indulging in a good drink.

A delightful read from the math teacher you wish you had

Math is often presented as dense and boring, but Cornell professor Steven Strogatz brings it to life with his digestible and entertaining writing style.

For someone who's new to math or wants a charming refresher, we recommend "Joy of X." But for those who are a bit more scientifically literate, we recommend "Sync," which explains how enormous systems synchronize themselves.

"The Foundation Trilogy"

Isaac Asimov's masterpiece is arguably one of the greatest science-fiction trilogies ever written. The galaxy-spanning epic revolves around a fallen empire and a brilliant mathematician's plan to shape history and preserve civilization.

This beautiful hardcover edition comes with a nifty endpaper galaxy photograph courtesy of NASA.

The classic — and secretly beloved — math-joke T-shirt

Let's be honest. Everyone loves a good math joke. And what better way than to put it on a T-shirt?

Bonus points if it's from the recipient's alma mater.

A subtle tribute to your "Star Trek" obsession

In the opening scene of a "Star Trek: The Next Generation" episode, Capt. Picard works on solving Fermat's Last Theorem, musing that it has still not been solved after 800 years.

Amazingly, British mathematician Andrew Wiles actually found the proof six years after the episode aired. And this was subsequently, subtly addressed in a later "Deep Space Nine" episode.

In any case, you can pay tribute to one of the best shows ever with this iPhone case.

Whiskey glasses for the college student scraping through multivariable calculus

Uncommon Goods

The higher dimensional thinking involved in multivariable calculus is initially jarring and enough to make anyone's head spin.

We recommend a good antidote of fine whiskey in some fine math-symbol-covered glasses.

A nifty roll-up chess set

A standard chess set isn't exactly portable. So if you're a serious player, investing in a roll-up board and a carry-on bag may be a smart move.

A Go board

If chess isn't your thing, consider picking up a Go set. The ancient Chinese game is so complex and nuanced that computer scientists have spent decades trying to make a program capable of taking on skilled human players.

A book or two from the inimitable Richard Feynman

Physicist Richard Feynman was probably just as well known for his bongo playing as he was for his physics work. But as colorful as his personality was, what really put Feynman on the map was his ability to explain complicated things in a way that people can actually understand.

If you're looking for a good explainer for some of the strangest parts of modern physics, we recommend "Six Not-So-Easy Pieces." But we also recommend his autobiography "Surely You're Joking, Mr. Feynman!"

An Arduino starter kit

This Arduino computer kit comes with 19 projects and is designed specifically for beginners.

It's a fun way to learn how to build simple devices, and makes a great gift for anyone who loves hands-on work and has an interest in computer science or electronics.

A 3-D printer pen

If you've ever wanted to draw in 3-D, we recommend scooping up a 3-D printer pen. You'll be able to bring your ideas to life "in the air."

This version is great for noobs and pros alike.
