If you are aware of an interesting new academic paper (that has been published in a peer-reviewed journal or has appeared on the arXiv), a conference talk (at an official professional scientific meeting), an external blog post (by a professional scientist) or a news item (in the mainstream news media), which you think might make an interesting topic for an FQXi blog post, then please contact us at with a link to the original source and a sentence about why you think that the work is worthy of discussion. Please note that we receive many such suggestions and while we endeavour to respond to them, we may not be able to reply to all suggestions.

Please also note that we do not accept unsolicited posts and we cannot review, or open new threads for, unsolicited articles or papers. Requests to review or post such materials will not be answered. If you have your own novel physics theory or model, which you would like to post for further discussion among then FQXi community, then please add them directly to the "Alternative Models of Reality" thread, or to the "Alternative Models of Cosmology" thread. Thank you.

Hi Seth,

I liked the animation you used for your video a lot and the way you explained how physics is involved in firing of a Nerf-gun bullet. Not many people manage to make what you did: make a educative, clever and really funny video without ever being pretentious or self-important. Next time I get my hands on a Nerf-Gun (which hopefully isn't in the far future) I will remember your video and what I otherwise mindlessly neglect: gravity, air pressure, friction or Newton's law of motion.

I wish you good luck and hope to see more of your videos,

Hi Seth,

This was a great choice of topics! Your explanation was concise, and your physics seems sound. Good luck!

If you could watch and rate my video, "The Cool Physics of Refrigeration," that would be great. Thanks!

Let go through some of the basics of Physics

Verification of Archimedes' Principle

Archimedes' Principle:

Archimedes' principle states that when as body is totally or partially immersed in a fluid, it experiences an upthrust equal to the weight of the fluid displaced.

Experimental verification Archimedes' principle

Materials required to verify Archimedes' principle are:

Eureka can, Stone, Beakers, Measuring jar and Spring balance

Arrange the eureka can and the beaker on the table as shown here. Pour water into the eureka can till the water starts overflowing through the spout. When water stops tripping replace the beaker by another beaker of known mass. Suspend a stone with the help of string from the hook of the spring balance and record its weight. Gradually lower the stone into the eureka can containing water and record the reading of the spring balance when the stone is completely immersed in water. The weight of the stone is found to be less than its weight in air i.e., the apparent loss of weight. We observe that the water overflows through the spout of the eureka can. Pour water into the measuring jar and note the reading. The observed reading gives the volume of water displaced. The volume of water displaced is equal to its weight as the density of the water is equal to 1. The apparent loss of weight of stone in water is equal to the weight of the water displaced by it. This proves the Archimedes' principle.
