NOVA: How the Brain Works The description pretty much describes this video well. In essence‚ it’s a look into the complexity of the human brain. Trying to understand how we perceived the world around us and showing some of the experiments that try to explain how the process works. If you want to spend an hour with quirky but interesting approach to the topics of how illusions work‚ how our brains are affected by electro-magnetic impulses and what is the current status of artificial intelligence

Olfaction or olfactory perception[1] is the sense of smell. This sense is mediated by specialized sensory cells of the nasal cavity of vertebrates‚ which can be considered analogous to sensory cells of the antennae of invertebrates. In humans‚ olfaction occurs when odorant molecules bind to specific sites on the olfactory receptors. These receptors are used to detect the presence of smell. They come together at the glomerulus‚ a structure which transmits signals to the olfactory bulb (a brain structure

How Does the Catapult Work? There is quite a bit of science behind the making of the catapult‚ and how it works. It is similar to a ballista that it works by storing tension in a flexed piece of wood or in twisted ropes. It’s similar to a bow‚ but on a much larger scale. However‚ that is just the catapult which is probably most

How the Predator UAV Works Military commanders use tactics and strategy in combat to inflict as much damage on the enemy while trying to risk as few personnel and resources as possible. This principle was at the heart of the development of the RQ-1 and MQ-1Predator Unmanned Aerial Vehicle. These high-tech aircraft‚ controlled by a crew miles away from the dangers of combat‚ are capable of reconnaissance‚ combat and support roles in the hairiest of battles. In a worst-case scenario‚ if a Predator

It also helps a lot when working with children in a setting‚ if you are planning an activity you can think about what risks might happen from the activity then you can assess on how to avoid those risks so they don’t happen. You can usually make your own mind up about what a risk is and then how to avoid it
