How I went from insomnia to the best sleep of my life (and how you can too).
Sleep. Some of us can’t get enough of it, while others are in a love-hate relationship.

For many years after becoming an entrepreneur, I was the latter. Like every human, my mind and body needed sleep to function. The problem was, I had trouble actually falling asleep in the first place.

Now, I will say that there are variances of how one would define an insomniac. I wasn’t suffering from chronic insomnia that could do serious damage to my well-being. However, there were many periods when I would only get two to three hours of sleep during the week.

If mild and periodic insomnia is something you face, or even chronic insomnia, read on. As my work, relationships, and overall energy began to decline further, I took serious action to research and ‘self-experiment’ on fixing my insomnia for good.

Can an Arrow Fired Straight Up Fall Fast Enough to Kill You.
In a recent episode of Mythbusters, Brian and Jon (the new MythBusters) wanted to see what happens when you shoot an arrow straight up into the air. It will obviously come back down—but would it still be moving fast enough to kill you? If you are a MythBuster, the best option is to actually shoot an arrow straight up into the air and measure its velocity on impact. But for normal people, it might be better to just calculate the final arrow speed. Also one note—I& #x27;m currently a science consultant for the show.

OK, let& #x27;s start with a basic physics problem. How fast would an object be moving if you dropped it from a height of 300 feet (91.4 meters)? When an object is in free fall, there is only the gravitational force acting on it. Since both the acceleration and the gravitational force depend on the mass, all objects fall with the same acceleration (regardless of mass) with a rate of g = 9.8 m/s2. Of course, this is only true if you ignore air resistance—but we will get to that soon.

If the object starts at a vertical postion y = h and ends at y = 0 meters with a starting speed of 0 m/s, then the final velocity can be found with the following equation. If you want more details on kinematics, here is a resource.

Using the starting height of 91.4 meters, I get a final velocity of 42.3 meters per second (which would be 94.6 mph). So right there you can see that this is a fairly nice estimation of the motion of the arrow. But that analysis leaves off one important aspect—air resistance. As an object moves through the air, there is a force pushing back in the opposite direction of the object& #x27;s velocity. The magnitude of this air resistance force increases with velocity and also depends on the air and the size of the object. This air resistance force can be written as the following equation:

Of course you can control your smart home with your underwear.
Just how close are you willing to get to your wearables? Smart underwear company Myant will soon find out.

The company's just opened up pre-orders for Skiin, its new line of "smart" underwear and bras, tech-filled undergarments that can track what's happening in your body and even control your smart home.

The tech is similar to Google and Levi's Jacquard jacket: an array of sensors are woven into the fabric and each undergarment is powered by a small, rechargeable module that can be removed from the clothing and charged wirelessly.
