Antibiotic Resistance

Sun, 17 May 2026 00:00:00 +0000

What doesn’t kill you makes you stronger

Have you ever wondered why you have to finish every single pill in an antibiotic course, even if you feel better halfway through? Stopping early might feel harmless, but it contributes to the catastrophic emergence of “superbugs”.

Biosafety Levels

Wed, 28 Sep 2022 00:00:00 +0000

How do we handle the world most dangerous viruses?

Have you ever heard of biological hazard and wondered what it means? You have probably seen this sign somewhere, but what threat does it imply and how dangerous can it be?

Graham's Number

Mon, 22 Aug 2022 00:00:00 +0000

What is the largest number you can think of?

Have you ever wondered what is the largest finite number you can think of? No it is not 40 (largest number on earth in terms of surface area). It first seems like a meaningless question, because no matter how large a number is, you can always go higher. But now we are going to talk about one of the largest finite meaningful number, the Graham’s number.

Industrial Revolution

Fri, 24 Jun 2022 00:00:00 +0000

How are you seeing this post here..?

Honey Bees

Sat, 14 May 2022 00:00:00 +0000

The wonders of nature… bees

N95

Thu, 24 Mar 2022 00:00:00 +0000

Masks.. an essential tool in the 2020s

One has seen the importance of masks to fight against diseases and the spread of viruses. Have you ever wondered how masks work, specifically the N95 masks? You might be thinking, all masks are like a mesh of fibers with gaps too small for dusts and other airborne particles to get through. But what’s so special about the N95 masks?

Selfish Gene

Tue, 28 Dec 2021 00:00:00 +0000

Every organism is selfish because of the gene..

Have you ever wondered about the origin of a species? Why are we all here? Where do we come from? The theory of evolution focus on how an organism compete for survival and how that competition shapes a species over multiple generation. If we look closely, the contest also plays out at a much finer level, level of the gene.

Rainbow Part 2: Color of Light

Wed, 08 Sep 2021 00:00:00 +0000

ROYGBIV

Have you ever wondered what the true colours of a rainbow are? Most of us learn that a rainbow consists of seven colours: red, orange, yellow, green, blue, indigo, and violet — or ROYGBIV for short. But if you look closely at a real spectrum, something seems odd..

Rainbow Part 1: Formation

Tue, 01 Jun 2021 00:00:00 +0000

Chasing the end of a rainbow

Have you ever wondered what brings this beautiful combination of colors to the sky when the Sun shines after a rainfall? Let’s talk about one of nature’s most stunning phenomena: the rainbow!

Black Widow

Wed, 27 Jan 2021 00:00:00 +0000

Another deadly romance story

It’s mating season, and male spiders are on the move looking for a mate… or are they? Have you ever wondered how black widow spiders mate, and why they are called “widows” in the first place?

Placebo Effect

Mon, 25 Jan 2021 00:00:00 +0000

Belief is the key to success

Have you ever wondered can our power of belief change our body physically? A placebo is something that shouldn’t work, but due to our power of belief, does! In medical field, placebo can have a powerful influence on the body, in some cases can even help the body heals. How?

Fermi Paradox

Sat, 23 Jan 2021 00:00:00 +0000

Are we alone?

Have you ever looked up at the night sky and wondered: are we alone in the universe? If intelligent extraterrestrial life is likely to exist, then why haven’t we found any evidence of it? The contradiction between the high probability of extraterrestrial civilizations and the lack of observational evidence is known as the Fermi Paradox.

Stars Part 2: Death

Thu, 21 Jan 2021 00:00:00 +0000

The death that creates life

When you look up at the night sky and admire the beautiful stars, have you ever wondered whether they have a lifespan? How long will they continue to shine? And perhaps more intriguingly, what happens when they die?

Stars Part 1: Formation

Tue, 19 Jan 2021 00:00:00 +0000

Gravity gave birth to the stars

Have you ever wondered how stars are formed? Why do they twinkle? There are an estimated 100 to 400 billion stars in our galaxy alone, and some are thousands of times larger than our Sun!

Grandfather Paradox

Sat, 16 Jan 2021 00:00:00 +0000

Let’s travel back in time

Have you ever wondered whether we could travel back in time? In the Special Relativity series, we learned that travelling close to the speed of light can, in a sense, allow you to travel into the future through time dilation. But what about travelling into the past?

Shape of Gravity

Thu, 14 Jan 2021 00:00:00 +0000

Every planet wants to become a sphere

Have you ever wondered why the Earth is round? Why are almost everything in space—planets and stars—round as well? Why isn’t the Earth flat? And if the Earth is round, why don’t people at the “bottom” fall off?

Morse Code

Wed, 13 Jan 2021 00:00:00 +0000

SOS: The message that means nothing

Have you ever wondered what you can do to call for help when you are stranded on a deserted island with no phone or internet? You have probably heard of SOS, the international distress signal used during emergencies. But what does it actually mean?

Artificial Intelligence

Mon, 04 Jan 2021 00:00:00 +0000

Will AI take over the world?

What is all the “hype” about AI? There is no doubt that the development of AI has changed people’s lifestyle drastically over the years. What do you know about it?

Neonatal Jaundice

Mon, 04 Jan 2021 00:00:00 +0000

Special Relativity Part 4: Beyond Light Speed

Fri, 01 Jan 2021 00:00:00 +0000

Let’s try going faster

Have you ever wondered, in this vast universe, whether anything can travel faster than the speed of light? In Part 1, we discussed that nothing can travel faster than light. So the universe’s ultimate speed limit is the speed of light… right? Maybe not.

Special Relativity Part 3: Length Contraction

Thu, 31 Dec 2020 00:00:00 +0000

Moving makes you look shorter

Have you ever wondered if the length or size of an object can change according to its speed or the observer’s speed? Sounds ridiculous, right? Apparently, motion not only affects time, it also affects how lengths are measured.

Special Relativity Part 2: Time Dilation

Wed, 30 Dec 2020 00:00:00 +0000

The faster you move through space, the slower you move through time.

Have you ever wondered is time travel really possible, like in the movies? Surprisingly, according to Albert Einstein and his theory of Special Relativity, travelling into the future may actually be possible. One of the strangest consequences of special relativity is something known as time dilation.

Special Relativity Part 1: Nothing Outruns Light

Tue, 29 Dec 2020 00:00:00 +0000

Schrödinger's Cat

Thu, 24 Dec 2020 00:00:00 +0000

Curiosity kills the cat

Have you ever wondered how curiosity can actually kill a cat? It’s not just a saying—it’s also tied to one of the most famous thought experiments: Schrödinger’s Cat, proposed by physicist Erwin Schrödinger.
