Here is a lovely little bit of information about deadly weapons that are still in use today, and should have been banned from there conception.  It sickens me they amount of time humanity spends on creating ways to kill each other.

What is so wrong about wanting to live with one another in peace? Actually talk to someone before you judge them? or bomb them...

Meditation

I am sure most of you have heard of this ancient practice, I am also sure a lot of you don't believe it is useful for anything.  Well you couldn't be more wrong, this is one of the best and easiest practices to start doing, and it helps reduce stress and anxiety.  As well as gain creative flow again, help you focus on tasks that previously frustrated you.  It is usually a daily routine set early in the mornings, but you can do it any part of the day, and it only takes about 20 minutes a day, you can however do it for much longer if you wish.

Meditation can also lead to out of body experiences if you practice long enough, you mind is the ultimate drug, why hurt and abuse your body with these chemicals when you can jump into the deepest parts of your mind and see them as vivid a dream or even real life if you have the knack for it.

Some of the benefits of meditation.

The Time Lens or Time Cloak

This little device is quite a large leap in humanity, this allows the user to temporarily pause or stop an event in time, maybe not quite to what you are thinking.  The main research that has been done on this is using the device to bend the temporal space time of light to make it slow down and speed up in certain parts of the beam, but it does not effect the over all beam of light, it basically still looks like a full beam of light although there is a sped up and slowed down section which creates a gap in the middle of the beam.

This can be use for something such as, a laser that sets off an alarm if you walk through it, this device would create a gap that you can pass through but the information for the detector never notices because the beam is still visually there entering the detector.

This has also lead to the development of the cloaking device, which I am sure a lot of you have heard of already.  It made is way into car commercials. (sadly) The quantum stealth blanket, is also a large jump for humanity, I just hope that it gets used properly...
