Why Elon Musk Wants to Implant an Electrical Wire in Your Brain

Elon Musk, the celebrity entrepreneur behind Tesla and SpaceX, finally unveiled what his company Neuralink has been up to for the past two years. Neuralink is developing a brain-machine interface, or BMI, with the goal of one day helping the paralyzed use robotic limbs or other devices. Musk even envisions a future where able-bodied people […]

Why Does Metal Rust? – Reactions Q&A

Well folks, you asked and we’re answering. That’s right we heard you. Peter Sterckx wants to know why do metal things grow. Well, here’s Sophia with an explanation. Corrosion is caused by a redox reaction, which is actually two simultaneous reactions in one: Reduction and Oxidation. (Oncscreen: 1) Reduction) A reduction reaction occurs when some […]

Electrolytic Refining of Metals | #aumsum

Our topic for today is Electrolytic Refining of Metals. Nice Jacket. Thank you. Hey. My Jacket. Our last participant is Mr. Smart. Electrolytic refining is the process of obtaining pure metals like gold, silver, copper etc. by the process of electrolysis. Electrolytic refining of copper. Take an electrolyte of acidified copper sulfate solution. Take the […]

Scientists Can Implant Fake Memories in the Brain, Here’s How

Human memory is unreliable enough as it is, but researchers interested in better understanding how and where our memories are stored are developing new ways to manipulate them. The search for memory “engrams,” a collection of identifiable neurons that physically represent a memory, has occupied scientists for over a hundred years. Turns out, memory is […]

What Are Metallic Bonds? | Properties of Matter | Chemistry | FuseSchool

Metals are used in many everyday objects. This morning when I woke up I decided to have a soft-boiled egg and a cup of coffee. The pot I used is made of metal. The kettle is made of plastic, but the coiled heating element inside it is made of metal. Metals are good conductors of […]

T4E – Setup procedure for Dynasty 350 (GTAW)

Alright. Today, we’re going to be looking at setting up our Dynasty 350 for Gas Tungsten Arc Welding of carbon or stainless steel. First thing we’re going to do is hook up our leads. We have our workpiece connection which goes with this symbol here. Make sure that’s snug. We have our electrode lead which […]

Definition of Voltage and Current (ElectroBOOM101-002)

Hi, now that you know the most accurate theory of how electron came to life, let’s get into electronics, but not quite yet. I can’t just tell you what the voltage and current are – the video would be too short. You won’t quite grasp the meaning. So when scientists were discovering electricity, they already […]

Why Haven’t Hydrogen Vehicles Taken Over the World Yet?

We were expecting hydrogen cars to take over the world years ago, but so far, we’ve got more Prius’ and Teslas. What happened to the fanfare for the car that runs on water, man? It’s been a while since we’ve heard anything about hydrogen cars, seemingly because the market wasn’t ready to look past it’s […]

Cut metal easily! – DIY Power hacksaw

Hi I’m Emiel, The Practical Engineer, and today I’m making this drill powered metal hacksaw To power the saw with my drill I need to convert rotary motion into linear motion. And I’m doing that by making an axle that fits onto my drill That has a point ,off-center, that moves like this. And when […]

How These Bacteria Become Electrical Cables That Could Power Our World

It turns out that bacteria may have figured out the whole electricity thing way before we did, you guys. In fact, there are bacteria deep in the ground and under the ocean right now that are acting as living electric cables, and scientists are coming up with all sorts of cool new ways to study […]
