Math uses in Real Life Engineering

By

 


Bro, ম্যাথ literally everywhere. তুমি ভাবছো শুধু exam আর CP তে লাগে? Nahhh—real life is fully math-coded. নিচে breakdown দিলাম কোন ধরনের math কোথায় use হয়:



---


🔷 1️⃣ Arithmetic & Basic Algebra


Where used:


bazar-shopping


bKash হিসাব


discount calculation


salary/loan


time–distance


cooking measurements



Vibe: real life survival skills.



---


🔷 2️⃣ Geometry 

Where used in real life:

land measurement

building design


architecture

map navigation

camera FOV

graphics design

drones & robotics path

game development

animation

computer vision


---


🔷 3️⃣ Trigonometry


Where used:

measuring tall buildings using angles


GPS

mobile network towers

3D graphics

sound waves


machine learning (loss functions, angles)

physics simulations

AC–DC circuits


---


🔷 4️⃣ Calculus (Differentiation + Integration)


Where used:


speed, acceleration

population growth

stock market prediction

AI/ML optimization

physics motion

engineering designs

area/volume calculation of weird shapes

traffic flow analysis



Real talk: পুরো AI আর neural network calculus ছাড়া অসম্ভব।



---


🔷 5️⃣ Linear Algebra (Most OP Modern Math)


Used in:


computer graphics

3D transformations

image processing

facial recognition

crypto

machine learning

deep learning (matrices everywhere)

robotics

physics engine



Basically — your whole modern world = matrices.



---


🔷 6️⃣ Probability & Statistics


Where used:


weather forecast


cricket score prediction


medical analysis


AI models


algorithms


fraud detection


polls & surveys


traffic prediction




---


🔷 7️⃣ Number Theory


Used in:


cryptography


password hashing


blockchain


compression


competitive programming CP


error detection in networks




---


🔥 If You’re a Developer Like You → Here’s the Exact Mapping


Geometry → graphics, UI/UX positioning, game dev, robotics


Linear algebra → machine learning, vision, deep learning


Calculus → optimization in ML


Trigonometry → animations, rotations, 3D


Number theory → security, hashing


Statistics → AI, data analysis




---


If you want, I can teach you each of these maths only with real-life examples instead of boring theory.


Want that?

AI is not scary: Why we should embrace artificial intelligence

By A.H.Raihan
  AI is not scary: Why we should embrace artificial intelligence Artificial intelligence (AI) is a term that refers to the ability of machines to perform tasks that normally require human intelligence, such as reasoning, learning, decision making, and creativity. AI is often seen as a threat to human jobs, privacy, and even existence, but in this blog post, I will argue that AI is not scary, but rather a powerful tool that can enhance our lives and society in many ways. First of all, AI can help us solve some of the most pressing problems that humanity faces, such as climate change, poverty, disease, and education. AI can analyze massive amounts of data, find patterns and insights, and propose solutions that humans may not be able to discover or implement. For example, AI can help us optimize energy consumption, reduce greenhouse gas emissions, predict natural disasters, diagnose diseases, design drugs and vaccines, and personalize learning. Secondly, AI can augment our capabilitie...
