Being a human isn’t an easy task. We often focus only on our exterior shell, but we forget about the wonders hidden on the inside. The human body is more complex than a computer. It is made out of tiny particles that form the cells that later form the tissues and organs to create the perfection that is the human organism. But in reality, we’re not all that perfect. What makes us different than just a random plastic object is that every second in our body there are a million of things happening all at once. Deep within our cells, the nucleus communicates with other organelles to keep the cell functioning. On a higher level, cells communicate with the ones surrounding them, organs communicate between themselves via blood and above everything else, the brain communicates with each and every particle in the body through hormones. Hormones give the orders to move a muscle, create a new cell, to <a href="https://rumble.com/v3noad-how-exercise-improves-your-mental-health.html" target="_blank">feel happy and to feel sad</a>. It is constantly happening, so the brain has devised a few shortcuts based on experience. Basically, what this means is that if something happens, we jump to the conclusion based on what our <a href="https://rumble.com/v3bet9-3-techniques-to-train-your-brain-like-a-mental-athlete.html" target="_blank">brain</a> tells us that has happened before and is the norm. But what if that’s not the case? What if those shortcuts lead us to misinterpret situations and make faulty decisions? Take a look at this video to understand why the human mind is imperfect.

Where are you right now? Until you interact with another particle you could be any number of places within a wave of probabilities. Matt dives into these counter-intuitive ideas and explains the bizarre phenomenon known as quantum tunneling in this episode of Space Time.

We've been through the first few episodes of our crash course on general relativity, and came out alive! But it's officially "time" for CURVED spacetime. Join Gabe on this week’s episode of PBS Space Time as he discusses Newton and Einstein's dispute over inertial frames of reference. Is Einstein's theory inconsistent? Is gravity even a force??? Check out the episode to find out!

Last year LIGO announced the detection of gravitational waves from the merger of two black holes. The science world went a little crazy. Only a few weeks ago a new rumour emerged: that LIGO had, for the first time, spotted gravitational waves from the collision of a pair of neutron stars. If it’s true, some long-standing astrophysical mysteries are about to be unlocked.

Sometimes bad things happen to good feedback.

Washing your hands is something we do every day – we wash our hands before eating, after using the washroom, while we’re cooking, we teach our kids the importance of wash their hands… It’s fair to say that it’s something we’re all pretty familiar with. But – have we ever really stopped and taken a closer look at why we wash our hands so frequently? Or - <a href="https://rumble.com/v4a4zd-proper-way-to-wash-your-hands.html" target="_blank">are we doing it properly?</a> Stop everything. Turns out you’ve probably been washing your hands wrong all this time and they could currently be riddled with germs. it’s a wonder we’ve managed to survive this long. Don’t be too alarmed though. There’s hope for us yet. The guys at You’re Doing it Wrong have come up with a YouTube video to help you figure out just how to get your hands squeaky clean. According to the Sklar Brothers most of us are not washing our hands properly after using the loo. it’s important to spend at least 20 seconds washing your hands after you’ve been to the toilet – something only five percent of us actually do, according to a Michigan State University study. Michigan State University discovered that 23 percent of people don’t use soap when washing their hands after using the loo, while 10% don’t wash their hands at all. The Sklar Brothers say we should focus more attention on our fingertips, since they are likely to be the most dirty. It’s also important to use soap (a quick rinse is not enough to kill germs) and use a paper towel rather than <a href="https://rumble.com/v3yvu5-maggie-does-not-like-the-hand-dryers.html" target="_blank">hand dryers</a> to dry hands off thoroughly - wet hands are worse than dry hands for spreading bacteria, and dryers don’t tend to get hands completely dry.

The search for a single number: the hubble constant, which is the rate of expansion of our universe, has consumed astronomers for generations. Finally, two powerful and independent methods have refined its measurement to unprecedented precision. The only problem is that they don’t agree. This calls into question some of our most basic assumptions about the universe.

Surprise! You're more optimistic than you think.

Ever since Adam and Eve used fig leaf to cover their nakedness, people have been storing fruits wrong. Every Sunday, millions of hipsters are at the farmer’s market filling their French mesh bags and free trade woven baskets with succulent pieces of ripe fruits. And every Monday, they find something on the counter that looks like elephant dung. Chances are, if you are eating fruit and vegetables, you are storing them wrong! Now, most of the people treat their refrigerators like a Japanese tourists hotel, everybody tucked neatly into their little drawers. That’s wrong! <a href="https://rumble.com/v328fy-5-fruits-you're-peeling-wrong.html" target="_blank">fruit</a> and vegetables need space for air circulation or they’ll spoil faster and start to spoil adjacent fruit. Many fruits produce ethylene gas, which acts like ripening hormone and speed spoilage. It’s the reason you should treat your unripe fruit like it’s been a beer on college campus- put it in a paper bag! The NCHFP explains that people began to preserve food as early as 12,000 BCE, by leaving meat and fruit out on the sun. So here we will learn what fruits and <a href="https://rumble.com/v3ngs3-how-to-regrow-common-vegetables-from-leftovers.html" target="_blank">vegetables</a> to store where. They should not be stored in the fridge. Also, basil should be out in a cup of water, not in the fridge. Onions, garlic, avocados, potatoes, coffee beans should be not put in the fridge. Root vegetables like broccoli, cauliflower, carrots should be stored in the fridge but for more freshness, you can wrap them in a wet cloth. Clever, right? Another great advice is to wait until the fruit is ripe before storing in the fridge.

The laws of physics are the same everywhere in the universe. At least we astrophysicists hope so. After all, it’s hard to unravel the complexities of distant parts of the universe if we don’t know the basic rules. But what if this is wrong? There is a hint of evidence that the fundamental constants that govern our universe may evolve over time, and even from one location to another.

The world's deadliest animal may be closer than you think.

It seems like some people have so many great ideas - like <a href="https://rumble.com/v31hih-did-einstein-know-the-truth-about-aliens.html" target="_blank">Albert Einstein</a>, who apart from changing everything we know about the whole of space and time, he also took a stab at fashion. Rest assured there are ways that the rest of us can be more creative, too. We explore some practical tips for boosting your creativity and generating ideas. Why do some people have so many great ideas? And how can the rest of us be more creative? Creativity is the result of large brain networks that interact with each other to generate random thoughts, change them and merge them and this happens through three mental skills: bending, breaking and blending. Bending is when we imagine things in new ways, breaking is when we take an idea and break it into pieces and blending is when we mix few things together. In 2017 study, researchers found those who score high on creativity tests have more connections between brain hemispheres and stronger communication between brain networks, and the people who come up with many original answers to a question possess a skill called divergent thinking. Remember that you are not stuck with the brain you have, your brain networks are flexible and you can practice creativity. So read more, pay more attention, visit a <a href="https://rumble.com/v45fql-museum-of-selfies-to-open-january-2018-in-glendale.html" target="_blank">museum</a>, and travel to feed your imagination. Keep generating ideas and come back to the ground with fresh eyes and hopefully fresh ideas. Don’t forget to surround yourself with interesting people. We need humans and our society for creativity to flourish.

If you were sleep deprived, could you just fake that you got more sleep the night before? Science has some interesting answers. Imagine you wake up thinking you had a wonderful night’s sleep, you feel fantastic and you are going to wake up immediately. However, no matter how much sleep you get there is always that niggling voice inside your head that you need more sleep and you are the thing about how tired you are. But, with simply thinking about how good sleep you had can improve your brain function. In a recent study, researchers told participants that those who spent more than 25% of their time asleep in REM sleep have better cognitive functioning. Simply believing that you had a good night’s sleep, even if you didn’t, it improves performance. But can you really fake sleep? Not really. But if you could stop thinking and talking about how tired you are, and plan a nap you could improve your sleeping. Researchers say that an afternoon nap is an ideal remedy for fatigue from sleep loss. But, that’s kind of unrealistic for us who have jobs and are not as brazen as George Constanza. One solution is active rest or progressive muscle <a href="https://rumble.com/v4hhw1-uwm-class-teaches-students-the-art-of-relaxation.html" target="_blank">relaxation</a>. You focus on one muscle, make it tense and then release. This will really help. While it’s really hard to tell what the quality of our sleep was actually like, you should snooze less and nap more. Or active rest. It’s almost <a href="https://rumble.com/v39z0j-power-napping-pug-snores-through-her-doggy-dreams.html" target="_blank">napping</a>. So it seems the key to fake sleeping is actually… Fake sleep.

Is there a limit to the number of relationships we can maintain?

Love is a complicated combination of brain chemicals and behavior that scientists are only just beginning to figure out. And it's remarkable that in every society that we have looked at on Earth, romantic love exists. So if love is so universal, and there are 7 billion other people out there looking for it, why can it seem like it's so hard to find?

Can You Solve This Riddle? This riddle first appeared in Grossman, Howard (1945). Scripta Mathematica XI TedED have a similar riddle that's beautifully animated: https://youtu.be/tE2dZLDJSjA

Why do we sleep? We spend a third of our lives in slumber, but science has yet to determine exactly why we have do it. Here’s a look at how sleep works, why we’re not getting enough sleep, what happens if you DON’T sleep, and an idea about where sleep came from in the first place.

This sleep cycle is a good average: your circadian rhythm can shift somewhat depending on your sleep/wake schedule. If you wake consistently at 9am, then your blood pressure with go up closer to 8:45am and everything else will be shifted as well. It's tied to sunlight A LOT but since we have artificial light, there's wiggle room within that.

In the digital age, we increasingly use written language in place of face to face chat or phone calls. But the advantages email, chat, and text give us in speed come with limitations in communicating emotional tone. Enter emoticons and emojis.

How is our brain put together? And where do these 'pieces' come from?

How can simple sound waves cause so much emotion? I went from my comfy chair to the streets of Austin to investigate how it might be written into our neuroscience and evolution. Modern neuroscience says our brains may be wired to pick certain emotions out of music because they remind us of how people move!

At the beginning of the Triassic Period, with the continents locked together from pole-to-pole in the supercontinent of Pangea, the world is hot, flat, and very, very dry. But then 234 million years ago, the climate suddenly changed for the wetter.
