How many watts of radiation is dangerous?
How many watts of radiation is dangerous? To cause death within hours of exposure to radiation, the dose needs to be very high, 10Gy or higher, while 4-5Gy will kill within 60 days, and less than 1.5-2Gy will not be lethal in the short term. However all doses, no matter how small, carry a finite […]
Why is a frame of reference needed?
Why is a frame of reference needed? A frame of reference is a set of coordinates that can be used to determine positions and velocities of objects in that frame; different frames of reference move relative to one another. This means that we can address problems in any reference frame to give an equivalent solution. […]

Can humans see microwaves?
Can humans see microwaves? The human retina can only detect incident light that falls in waves 400 to 720 nanometers long, so we can’t see microwave or ultraviolet wavelengths. This also applies to infrared lights which has wavelengths longer than visible and shorter than microwaves, thus being invisible to the human eye. Why can’t our […]
How much more powerful is fusion than fission?
How much more powerful is fusion than fission? Abundant energy: Fusing atoms together in a controlled way releases nearly four million times more energy than a chemical reaction such as the burning of coal, oil or gas and four times as much as nuclear fission reactions (at equal mass). Does Fusion produce more energy than […]
