That’s because relativistic mass is simply the same as energy, divided by a constant — namely, c² — and so, if you define mass to be “relativistic mass“, then different observers disagree about an object’s mass m, though all ...
The Moment Of Inertia Tensor Mass is a measure of translational inertia. The greater the mass of an object is the more it refuses to get accelerated for a given force. Similarly, the moment of inertia is a measure of rotational inertia. It depends on both the mass and the distribution of...
Why is sci-fi helpful to society? Why should we not use a Mantel-Haenszel summary measure of effect when interaction is present? Is there a specific order in which the four causes of Aristotle must be explained? What is the structure of a thermocouple and why does it need to be amplified...
In 1915, Albert Einstein figured out the answer when he published his theory of general relativity. The reason gravity pulls you toward the ground is that all objects with mass, like our Earth, actually bend and curve the fabric of the universe, called spacetime. That curvature is what you ...
生き甲斐, pronouncedikigai, is a Japanese concept that means “reason for being.” In other words, what makes you get up in the morning without an alarm clock because you're so damn excited?! Ikigai is at the heart of Financial Samurai, this personal finance site I created in 2009 to ...
Amnesia: A Machine for Pigs Sequel to the best horror game of all time. This project is pretty much dream team-up, because Frictional is working with Chinese Room, which was responsible for the incredible Dear Esther. Cherry Tree High Comedy Club ...
nonetheless, the nature of a crowd changes from a heaving mass of anonymity when full to slightly awkward and bashful when sparse, if peppered with noisy defiance (at least in the first half, we’ll get to that). There are plenty of faces here who’ll remember those days though. Briefly...
At present, an optimistic peace process is being fuelled by civic society, and there is an attempt to avoid confrontational inertia between the ETA (Euskadi Ta Askatasuna, or Basque Country and Freedom, the armed Basque nationalist and separatist organisation) and the Spanish state (Mediapro, ...
Why the moment of inertia is a tensor? If energy creates gravity, why is gravity not energy? Why does time get slower near a black hole? Why heat is called the disordered energy? Briefly explain why the 2s and 2p energy levels are at the same energy for Li^{2+}. ...
Why is time not considered a form of energy? How will the period of a simple pendulum change when its length is doubled? Why does the period of a simple planar pendulum seem to be independent of the mass at the end of the pendulum string? It was sug...
