Easy strategy to deal with most physics problems in homework or exams, or just for fun. Stop panicking, and become a physics whiz!

Fermion calculator helps you calculate physical equations with the use of constants. Pick the right constant from the list, and use it properly for your calculation.

We can barely make out our own planet from the edge of our own solar system. Do you think we can see man-made structures from the center of our galaxies? Of course not. Does that mean they’re not visible from space?

Astrologers claim that the positions of the planets and “Zodiac” signs (constellations of stars) at the moment of our birth – and generally throughout our lives – affect our personality, mood and affairs.
We are going to test this hypothesis.

I thought it will be interesting to share this essay with you, as it was an exercise in critical thinking, one that I enjoyed researching. It raises some important issues about the scientific method and how important it is for scientists to constantly make sure they follow it.

Richard Saunders (Australian Skeptics, Skeptic Zone podcast, and more) brings the astrologer back to Earth and away from fantasy.

The “losing weight” trend is one of the better outcomes of reality TV, and it encourages people to take charge of their lives and live a healthier life. But there’s one thing that bugs me about this trend: The terminology.

Ramon’s personal diary fell close to 37 miles (almost 60 km) through the extreme conditions of re-entry. Unlike its human owner, it has survived the process and is now being restored and presented to the public in the Israeli Museum in Jerusalem.

A few months ago I released an experiment video explaining how Eratosthenes calculated the circumference of the Earth using the shadow of sticks. The method was performed almost two millenia ago, and produced quite accurate results (considering the ‘equipment’ used). But it was far from being the only (or first) method to understand our planet’s [...]

The Olympics Games are here (well, in Beijing) and everyone’s watching and trying to guess who will win a medal. But, apparently, even the Olympics is a source of scientific inquiry, and not just for geeks. The “Speedo” controversy raises some interesting points about the effect of a swimsuit on the swimmer, and the effect [...]
