Diophantus of Alexandria – Scientist of the Day

Diophantus of Alexandria was a Greek mathematician of, we believe, the 3rd-century C.E., although he could have lived 300 years earlier and we could not tell.

This is not really related to my usual posts about fanfic, but it’s my blog so I can say whatever I want.

I went away with friends for a trip this last weekend and they have split the expenses up using a website called Splitwise. You enter in who paid what and on behalf of which person, and the website tells you how much everyone owes one another.

And.

Like.

I’m really, really struggling to see what the point of this is. There are only three of us. The maths is so incredibly simple.

You cannot tell me you need a fkg website to calculate how much everyone owes each other. You add up what one person paid on behalf of another, and then deduct the reverse. This feels like something you can do on paper. Or, if you really want to get fancy, in Excel.

But a website that does it for you? Have we really fallen so far as a society and are so reliant on technology that we can’t do some simple maths? I questioned why we were using this and one of my friends told me that it made everything easier because you can even split uneven amounts for a bill, like for dinner.

But.

?

What? What?

I don’t see how this is a benefit. I’m still having to get a calculator out to add up the amount that has to be paid so I can enter it into the website, what’s the point of the website?

I’m a big fan of tech. I am. But not when it replaces thinking like this. This use case is not a good enough reason to outsource some baby maths to a website. It makes no sense.

Today ( January 29) is the 100th BIRTHDAY Anniversary to ABDUS SALAM 1st Muslim Nobel Laureate…


Abdus Salam — 100th Birthday Anniversary (29 January 2026)

Mohammad Abdus Salam was born on 29 January 1926 in Jhang Maghiāna (then British India, now Pakistan). In 2026 the world is marking the centennial (100th) anniversary of his birth, with events and tributes across scientific communities — especially at the International Centre for Theoretical Physics (ICTP), the institution he founded to support physicists from developing countries. �


🎓 Who He Was

Abdus Salam was a Pakistani theoretical physicist renowned for his foundational work in particle physics and the standard model of fundamental forces. He was the co-recipient of the 1979 Nobel Prize in Physics alongside Sheldon Glashow and Steven Weinberg for contributions to the electroweak theory, which unifies the electromagnetic and weak nuclear forces. �


🏆 Major Scientific Contributions

1. Electroweak Unification (Weinberg–Salam theory)

Salam’s most celebrated achievement was the mathematical unification of the electromagnetic force and the weak nuclear force into a single framework (the electroweak interaction). This work was a cornerstone of the Standard Model of particle physics and predicted phenomena (like weak neutral currents) later confirmed by experiment. �


2. Quantum Field Theory and Particle Physics

He made significant advances in quantum electrodynamics (QED), renormalisation techniques, and contributed to early ideas about neutrino theory, symmetry in particle interactions, and components of the Standard Model. �


3. Theoretical Models Beyond the Standard Model

Salam helped develop theoretical frameworks such as the Pati–Salam model (an early grand unified theory) and explored ideas in supersymmetry and related mathematical structures — efforts that have influenced later work on unification of forces. �


🌍 Founding Support for Science in the Developing World

4. International Centre for Theoretical Physics (ICTP)

In 1964, Salam founded ICTP in Trieste, Italy, to foster scientific research and collaboration among scientists from developing countries. ICTP continues to be a leading institution for research and training, and it is central to the centennial celebrations held through 2026. �


5. Science Diplomacy and Education Advocacy

Salam was a lifelong advocate for scientific education and capacity building. He believed that scientific knowledge should be a shared global heritage and actively promoted research opportunities for scientists from under-represented regions. ICTP’s Spirit of Abdus Salam award and annual lectures honour this legacy. �


🇵🇰 And His Broader Legacy

He was the first Pakistani and first Muslim scientist to be awarded a Nobel Prize in science. �

Encyclopedia Britannica

Salam contributed to science infrastructure in Pakistan, holding influential roles in government science advisory positions early in his career; he also helped establish research groups and institutions, though some roles later became controversial due to political and religious tensions. �


His name continues to be associated with physics education and research: for example, the Abdus Salam Chair in Physics at Government College University (Lahore) fosters theoretical physics research in his honour. �

Wikipedia

🗓️ Centenary Events (2026)

In celebration of what would have been his 100th birthday year, ICTP and partner institutions are hosting:

Annual Salam Distinguished Lectures

Panel discussions on quantum science and technology

Advanced workshops and schools on contemporary physics topics

Awards in his name recognizing contributions to science in developing regions �

The Pythagoreans called the monad ‘intellect’ because they thought that intellect was akin to the One; for among the virtues, they likened the monad to moral wisdom; for what is correct is one. And they called it 'being,’ 'cause of truth,’ 'simple,’ 'paradigm,’ 'order,’ 'concord,’ ‘what is equal among greater and lesser,’ 'the mean between intensity and slackness,’ 'moderation in plurality,’ ‘the instant now in time,’ and moreover they called it 'ship,’ 'chariot,’ 'friend,’ 'life,’ 'happiness.’

Thought of something stupid today that I’d like to call

✨ Arithmetic Cypher

So essentially it’s like Caesar Cypher but instead of moving each letter’s alphabetical value (a = 1, b = 2, etc.) a fixed amount forward, we multiply it by a given amount instead, i.e.: if that value is 2 then a => b, b => d, d => h, etc.. and if it overshoots 26 then we just loop back to A

So use the key below to decode the message (pretty please 🥺)

explaining to my new boss that when i am first presented with an arithmetic problem like 64-39 my brain panics and starts shouting out random numbers like 22! oh 14! is it 18! and i have to calm it down before i can do the problem in my head

I know I’m talking about a fandom that’s niche and as dead as dust…

But I’ll forever be crying about 7 Hotties All My Husbands and Several Shades of Sadism being discontinued. These ikemen will always live in my mind.

I wasn’t fast enough to record everything too 😭

arithmetic (n.)

“art of computation, the most elementary branch of mathematics,” mid-13c., arsmetike, from Old French arsmetique (12c.), from Latin arithmetica, from Greek arithmetikē (tekhnē) “(the) counting (art),” fem. of arithmetikos “of or for reckoning, arithmetical,” from arithmos “number, counting, amount” (from PIE *erei-dhmo-, suffixed variant form of root *re- “to reason, count”).

The form arsmetrik was based on folk-etymology derivation from Medieval Latin ars metrica; the spelling was corrected early 16c. in English (though arsmetry is attested from 1590s) and French. The native formation in Old English was tælcræft, literally “tell-craft.”

From what I’ve learned in accounting classes, accounting is mostly just basic arithmetic, which just makes it all the more embarrassing that I’m so fucking bad at it

Mathematics, grade 4, word problems (real world math)

Note, this post has been edited from its original version to address significant errors.

Do Now:

Road sign showing three different models of commercial vehicles and a weight limit, One with two axles and a limit of 8 tons, one with three axles and 12 tons, and a combination vehicle with four axles and 16 tons.ALT

It’s important for truck drivers to know how much their vehicle weighs, because heavy trucks cannot drive on certain roads.

Unfortunately, you do not know how much your truck weighs. You tried looking it up in the driver’s manual, and on the internet, but nobody can tell you how much your truck weighs.

Until today! You are delivering lots of chemicals to a company that shall remain confidential. For security, this company has a massive scale at both the entrance and exit so they can make sure that delivery people like you aren’t driving away with any stolen goods.

When you enter, you have to stop on top of a giant scale. It says your truck weighs 33,400 pounds.

However, this is not the true weight of your truck, because you came here with a lot of cargo. Each weight below includes the weight of the shipping container.

  • 2,200 pounds of sodium carbonate peroxyhydrate powder
  • 6,210 pounds of sodium hydroxide solution
  • 2,560 pounds of a special chlorine solution (you don’t know what’s in it)

Before you leave, you drive over to a parking lot where a speaker plays the sounds of exotic birds on a constant loop. Each bird call happens one at a time with an eerie silence in between. There are no trees, only beige concrete. (You cannot share any footage of this bizarre experience, however, because you signed a “no photography” waiver, and you don’t want to lose your job 😋) Here, you acquire 2 empty chemical containers, each weighing 125 pounds, and two bigger empty containers each weighing 300 pounds. You also acquire the feeling that you’re being haunted by an angry kookaburra.


As you drive away, the scale at the exit says your truck weighs 23,080 pounds.


  1. Calculate how much your truck will weigh when it is completely empty.
  2. Share your calculations with a classmate. Did you get your answers the same way? Come up with reasons why you might have two different weights.
  3. Your truck has 3 axles. Could you have driven on a road with the sign pictured at the beginning of the problem? (1 US ton = 2,000 pounds)
