A disposable baby nappy is actually quite a cleverly designed product, the current iterations consisting of five different layers, each with its own specialized role to play. Furthermore, the superabsorbent polymer in the diaper’s core is unbelievable in terms of its ability to soak up massive amounts of liquid!
EngineerGuy, otherwise known as engineering professor Bill Hammack, is a well known science and technology documentarian who has gone ahead and put together this very informative video on what is quite an… absorbing topic:
As much as I moan about the cost of nappies, these brilliant little things really do make life with a baby/toddler so much easier!
Have you ever wondered just how fiber optic cables actually work? Well sure it probably has something to do with light seeing as the word optic appears in the name, but exactly what role does it play?
Well, if you are curious about this technology then you happen to be in luck – engineering professor Bill Hammack, a well known science and technology documentarian and face of his engineerguy.com project, has put together a very informative video that highlights the principles in play, and brings everything down to a level at which most of us can understand.
So let us allow Bill to get on with it then…
Undoubtedly a remarkable feat of engineering and definitely something that has made it possible to properly make the world an even smaller place!
Engineering professor Bill Hammack is a well known science and technology documentarian who has been the face of his engineerguy.com project for quite a number of years now.
In this video he explains how it is that a smartphone knows whether it is orientated in landscape or potrait mode – essentially whether it lying on its side or not.
(I’ll give you a hint: it’s because of the accelerometer).
Besides taking us through the concept of the accelerometer, Bill also gives us an idea of just how exactly one of such tiny size is actually created by engineers in the first place!
I think it is absolutely amazing (and mind boggling!) when one starts thinking at the tiny scale engineers need to think and reproduce these inventions at.

This time around he takes us through the engineering choices underlying the design of the worldwide icon that is the beverage can. He explains why it is cylindrical, outlines the manufacturing steps needed to created the can, notes why the can narrows near it lid, show close ups of the double-seam that hold the lid on, and details the complex operation of the tab that opens the can.
In other words, it turns out that quite a bit of thought has gone into the design of our modern day soda can.
