In 1970, British mathematician John Conway devised a way to quickly calculate the weekday of any given date without the help of calculators, computers, or calendars. It is called the doomsday algorithm and the best thing about this algorithm is that your friends will think you have a superhuman memory, when all you need to do is memorize a set of numbers and do a series of simple calculations. Conway <a href="https://rumble.com/v368l7-algorithm-for-crime.html" target="_blank">algorithm</a> bases on the fact that some dates always fall on the same weekday within any given year. These dates are called doomsdays. There are plenty of scary doomsday formulas out there, but how about those of us who don't hold a degree in mathematics? There are couple of steps to do this, the first one is to memorize weekdays as numbers because according to Conway, each weekday is represented by a number, for example: Sunday is 0, Monday is 1, Tuesday is 2 and so on. You need to memorize these numbers before moving on. As a mental anchor, it may be helpful to think of Tuesday as “Twosday”. To determine the <a href="https://rumble.com/v30os8-10-doomsday-predictions-that-didnt-come-true.html" target="_blank">doomsday</a> of the year in question, you have to follow a series of 6 simple calculations. Before you start, don't forget to memorize the weekday numbers and century anchor days and the most important thing is no to give up. This might sound awfully complicated at first, and most of us will need a good minute or three to go through all the steps. But with a little practice things will soon pick up speed. If you want to find out a more detailed info about any day, just watch the video to the end.

It’s been estimated that 1 in 10 works of fine art are forged or misattributed. The truth is, no one really knows how much fake art is out there, because many art counterfeiters are so skilled that their paintings are almost indistinguishable from the real works. But even counterfeiters can’t beat physics!

The weird and wonderful science of goose bumps. Hope you didn't get the chills. It is amazing how evolution has given the human body some odd parting gifts. The human body has been a work in progress for about the last six million years, so it’s understandable if over that time we have outgrown some of our components. Did you know that your appendix used to help digest plants. Since our diet isn’t that plant-heavy anymore, it only causes problems like appendicitis. Given, the early humans moved their ears for peripheral hearing, some of us can still wiggle our ears just for fun. It is curious that one bit of the corner of your eye was once bigger and served to protect and moisturize the eyeball. Now, this same feature only keeps dirt out off your eyes. It doesn’t come as a surprise that our ancestors had an extra muscle to help them hang from trees. Touch your pinky to your thumb and if you don’t see it, you are among the 10% of humans who lost it. Even our ancestors never made use of male nipples. They most likely form in the embryonic stage when we are essentially sexless. Knowing that your tiny tailbone is a relic of the mammalian tail is somewhat astonishing. Humans are believed to have lost their tails when they started walking upright. Our ancestors needed strong molars to chew through raw meat. When we learned to cook, our jaws shrunk and left no room for what we call wisdom teeth. Body hair kept our ancestors from freezing. Now, we no longer need <a href="https://rumble.com/v37srv-10-benefits-of-baking-soda-for-hair-skin-and-body.html" target="_blank">body hair</a> to do all of our temperature regulation. Also, goosebumps fluffed up our hair to keep us warm. Now that we wear sweaters and coats, there’s no need for goosebumps anymore. The human brain has been getting smaller in size over time. We are not getting dumber, our brain just works faster while taking up less space. If you happen to be interesting as to why or how <a href="https://rumble.com/v3rb8j-prepare-for-goosebumps.html" target="_blank">goosebumps</a> play their role onto our body, this video will come in hand and prove to be very useful and educational. Enjoy!

What do we mean by "normal"? Cognitive scientists have found that your notion of normality is shaped by the average (like statistical norms and hard data we have about things) and your ideals (the beliefs you hold). So our sense of normal is all a little different – knowing this can help us understand other views and how our perceptions can change.

Many think eating carbs makes you gain weight, but carbohydrates are your body’s main fuel source. This is what happens in your body when you eat carbs. To maintain a healthy diet; the key is to eat carbs, protein, and fat in moderation, focusing on giving your body, and brain, the fuel it needs, without going overboard. I *love* pasta – but go for a regular serving size... and not all-you-can eat

Why do you get a brain freeze? Sometimes, after ice-cream or a cold drink, it can feel like your skull is squeezing in our your brain – it can even be pretty painful. The cold temperatures are picked up by pain receptors near your palate, so while a brain freeze feels like a headache, it's actually just referred pain from your mouth. Keep watching for a few ways to get rid of a brain freeze... as
