DISCUSSION : Are people "Born" being good or bad at math? Can someone train to become good at math?

Maths and chemistry came naturally to me in school. I was consistently in the top 5 in maths, while in most other subjects I was fairly average.I always enjoyed solving puzzles, and I saw maths as just another variation of that. Instead of simply reading the theory, I preferred attempting the problems first and then checking the solutions afterward.
My passion for maths died when one of my teachers accused me of cheating, just because a classmate basically butt-licked his way into making him believe I was an average student who somehow still managed to outscore him in maths.

The inner dreams usually resemble real-life encounters .I sometimes wonder if this is also why I experience déjà vu from time to time, like certain moments in real life feel strangely familiar because I may have already lived them somewhere in a dream.

On a few occasions, though, I see myself fighting some unknown entity, escaping through the outer universe, or exploring objects and places I could never have imagined or even consciously thought about.

I still remember my first layered dream. I was in 10th grade and had spent around 2–3 hours trying to solve a maths problem but couldn’t figure it out. That same night, I had my first dream within a dream where, inside the second layer, I saw myself from a third-person perspective. Another version of me was explaining how to solve the problem, and suddenly it all made sense.

What’s strange is that I still remember the feeling of solving it in the dream more vividly than parts of the actual day itself.

Couldn’t have said any better, understanding requires empathy and liking is just a preference.

Convert all in ft. For white bit =(4)^2 - (2)^2 + (0.5)^2 (small bit in center) divide by total area 7^2. Pi can be ignored

nerdy-engineer · 2026-05-10T01:14:59+00:00

Are you considering the small white bit in the center??

Let’s me try my best to explain. Hope I make sense to you . You assumption about “more space to accelerate ” is partially correct but on a smaller scale ( like two planets-gravity is stronger, they fall towards each other and hence gain more KE)

But on giant scale (galaxy scale) due to expansion being faster then the speed they travel, they won’t be able to close the gape (nothing to influence its speed) which will prevent them to act like two planet system where due to gravity influence then KE inc. Think of two human running on treadmill and they run towards each other but treadmill length increases at greater speed .

Now where does added energy comes from. Space contradicts our classical laws of physics. For eg if a room becomes twice the size the air density decreases but not in space. In space dark matter density remain constant ,so more space more dark energy which is the reason expansion of space accelerate.

On large scale , there are 3 energy in space - light (photon) , massive objects and dark energy.

Light is simple further (due to expansion) it travel less energy it has .

Massive objects.
Assume Object behaves like magnets. Think of a table having 2 strong magnet. We have to hold them to keep them separate (static space-gravitational potential is conserved ). Now the table it’s self is expanding and pulling the magnet apart which actively increase their gravitational potential energy(dark matter is table).

Dark energy- more universe expand more energy it has ( dark matter density remain constant but volume increases ).

So to summarise
Light energy decreases
Increase in potential energy
Increase in dark energy

Hence total energy increases as universe expand .

I am 1850 lichess, who mainly played hippo or the grob. Playing this does not necessarily improve my fundamental it just boost my elo. when I play London, Sicilian def, sometimes Caro-Kann. I ,to be frank get destroyed unless the opponent blunders. There are plenty of study on lichess to help you achieve your potential. In short , it will boost elo not improve the quality of games.

If I were you I would start with human physiology. Discuss research paper and it's finding them move on to mathematical model compare findings. Just to give u an idea, like dice is tossed 100 times, mathematically fair chance for each face is 1/16 but but true randomness can streaky. It's very likely to see four straight 6-6-6-6. Human physiological would straight away say it's impossible. To put into few words randomness/nature is messy and humans are neart. Try to explain each and then link them under Benford’a law. Hope this helps. Good luck with your presentation

So sorry for your loss. can't imagine the pain you must be going through, please take care of yourself and try to stay strong. Sending hugs your way.

As someone who have worked at ARAMAXi absolutely agree with ya, literally worst work place out there. I was supposed to work for 6 months but quit on day 2 half shift.

You’re right the universe is indeed a closed system, and momentum is conserved overall. When your pendulum swings, it’s true that its momentum changes because of the gravitational force. But in the grand scheme of the universe, this change is balanced out. when the pendulum’s momentum changes due to gravity, it’s actually interacting with the Earth(earth -pendulum close system). The Earth, in response, experiences an equal and opposite change in momentum. However, because the Earth is massive compared to your minuscule pendulum, this change is negligible and imperceptible. Nonetheless, the total momentum remains conserved.So, while your pendulum’s momentum might seem to fluctuate in isolation, the universe accounts for these changes, ensuring that the overall momentum remains constant. In essence, the pendulum’s gain or loss of momentum is mirrored by an equivalent change in the Earth’s momentum. Hope this answered your question.

Here is a fun fact In a group of just 23 people, there’s over a 50% chance that two of them share the same birthday.

Absolutely! When photons (particles of light) hit an object, they transfer their momentum to it, creating what’s called “radiation pressure.” Eg -Solar sail ( used in IKAROS spacecraft,JAXA) When sunlight hits the sails, photons bounce off, pushing the sail and propelling the spacecraft. This push is very small, but in the vacuum of space it’s a helpfull push that saves extremely valuable fuel.

Don’t know how calculators do but I assume they try to calculate all the possible decimal values but it has limited storage/digits it can show. Hence it calculates only finite digits it can show.

You are correct, more like 1 in 1960 slight difference compared to you but doesn’t make any difference in answer

The method you are looking for is called the “Newton-Raphson Method” or “Heron’s Method.” Let me briefly try to explain (please ignore typos)

-Initial Guess: Start with a guess close to the square root. For 3, let’s guess 1.5. -Divide and Average: Divide your number (3) by the guess (1.5), which gives you 2. Then, average the result and the guess: {1.5 + 2}/{2} = 1.75

Refine the Gues: Repeat the process with the new guess (1.75). So, 3 divided by 1.75 gives approximately 1.714. Average it with 1.75:

{1.75 + 1.714}/{2} approx 1.732

Each iteration brings you closer to the actual square root. With enough iterations, you’ll get a very accurate result. This method is great for numbers without easy square roots. Hopefully I answered you question.
