Researchers at NUS just 3D-printed metal circuits in mid-air using a system called CHARM3D ⚙️✨ It uses Field’s metal — a low-melting alloy that cools fast enough to hold its shape. The result? Wires that conduct, bend, and heal when reheated 🔥 #Tech #Innovation #3DPrinting
Why can’t you divide by 0? 🤔 Dividing 15 by 3 means subtracting 3 until you hit 0 — five times. But with 0, you’d subtract forever! 🚫 As the denominator nears 0, the result explodes to ∞ or -∞. So math marks it as ⊥ (undefined) — even leading to Wheel Algebra! 🤯
Integral tip: ∫ cos(2x)cos(x) dx → use product‑to‑sum: cos2x·cosx = ½[cos x + cos 3x] ⇒ answer = ½ sin x + 1/6 sin 3x + C. #Calculus #Integration #Trigonometry #STEM #Maths #ExamPrep

“In my whole life I've never been good at something I wasn't very interested in. It just doesn't work. There's no substitute for strong interest.” — Charlie Munger
In the 1970s, Soviet scientists began one of the most ambitious experiments in human history - the Kola Superdeep Borehole in Siberia. Their goal? To drill as deep into the Earth's crust as technology would allow, to study the planet's inner layers firsthand. Over two decades,…
🚀 Jeff Bezos: AI Data Centers Will Move to Space Amazon founder Jeff Bezos believes that within the next 10–20 years, massive data centers for training AI models will be built in outer space. Why? 🌌 In space, there’s unlimited solar energy available 24/7, no atmospheric…

In 1876, Peter Guthrie Tait introduced the unknotting number — the fewest crossing changes needed to turn a knot into a loop. In the 1930s came the additivity conjecture: combine two knots and their unknotting numbers should add up. It held for decades — until Susan Hermiller…
