Why do things that are warm or heated up have more of a scent than things that are cold?
You smell things because particles of the item are floating in the air and registering in your nose. If you heat something up it makes substances more volatile. This just means that since the thing is
Why does more electronic storage cost more?
In some cases, the manufacturing process is a lot more complex to make the item that has more storage, even if it isn't physically any bigger. In other cases, they make many storage devices, all with
Why must we let a steak “rest” for best flavor, but that just makes it cold?
You just need to let it rest for 5-10 minutes before cutting into it. When you cut it right away after removing from heat, you will notice the plate will fill with liquid. That liquid is full of flavo
Why can’t Iran have nuclear weapons
From a treaty standpoint, Iran signed the Nuclear non-proliferation treaty that states that countries without nuclear weapons will not develop them. From a practical standpoint, Iran has been very ope
Why are plants green instead of being black? Wouldn’t black allow for more energy absorption.
Too much energy can actually kill the plant. It can lead to formation of what are called free radicals, highly reactive molecules that contain oxygen atoms that cause chain reactions in their chloropl
why do modern rockets blast off with zero initial velocity (standing straight up)?
The biggest difficulty in getting enough speed to get to orbital velocity is how the earth's atmosphere slows you down. It is most effective to blast straight up until the atnosphere becomes thinner a
Why is it that when you’re in the dark, staring directly at a light makes it less visible than looking beside it?
Your eyes are made up of two different types of receptors: cones and rods. Rods are for low light vision, while cones observe the colors and work in 'normal' lighting conditions. Those cones and rods
Why are most, if not all, workplaces based around a dictatorship style of governing?
Dictatorships are extremely effective ways of getting things done. I'm not aware of any successful company that's run in a fully democratic way -- even the employees at Valve either did what Gabe Newe
Why don’t birds get cold in the wind?
Birds have insulating feathers called *down*. They trap air close to the body so convection (moving air currents) can't pull heat away. To get their feathers to do this, their muscles can make the fea
Why don’t phones just capture video in horizontal mode no matter which way you hold it?
The actual sensor in the phone that captures the image is itself also rectangular - in the same direction as the phone screen. To make the phone record video in horizontal mode when it is held vertica
