Transistors how do transistors work. In this video we learn how transistors work, the different types of transistors, electronic circuit basics, how to build a transistor circuit, transistor amplifier, current gain beta, npn, pnp, heat sink, electronics and electrical engineering. Plus more! LEARN
Is it better for the child to switch off baby monitoring devices as often as possible? We explain why this is not necessary - and what can still be done preventively. Original: "Federal Office for Radiation Protection" Original: German. All translations in this video have been done by the alugha A
In this video segment adapted from NOVA, evolutionary scientist Sean Carroll investigates why one species of fruit fly has wing spots while another genetically similar one does not. As the video explains, although two organisms may both possess the same gene linked to a particular trait, this trait

Hello my dear tutorial lovers, This tutorial is for everyone who can do the crougar and toad perfectly. I explained this in my previous video. The four basic Jump Rope toads: Crougar, Toad, inverse toad, elephant. I hope that helped you getting into the toads. Not this is advanced level: awesome
The flick of a switch, that’s how easy it is to get electricity, right? If you’re one of the lucky ones, then yes. But in 2017 there are still over 1 billion people who do not have access to electricity. In this video we will discuss how electricity is generated and transferred to our homes, for th
Every operation has an opposite. With functions the opposite is called the inverse function. It undoes the function and returns you to the initial input. There is a simple process to follow to find the inverse of any function which we look at in this video. 1) Start by writing the function as y=
Do you often dream about success? What do you see in those dreams? Money, luxury cars, a big house, a good career? You may look at successful people and wish you could switch places with them. On the outside, they seem like they have it all, and it seems like they lead perfect lives. But on the ins
Reports of GNSS interference in the Baltic Sea have become almost routine — airplanes losing GPS, ships drifting off course, and timing systems failing. But what happens when a group of engineers decides to build a navigation system that simply *doesn’t care* about the jammer? Since 2017, we’ve bee
Are you having trouble determining if your crush likes you back? Or maybe you’re dating someone, but aren’t quite sure if they genuinely like you. There are some interesting signs like the eye brow flash that suggests they like you, because it's a subconscious behaviour. Writer: Michal Mitchell Sc
