23. Eat more foods that grow on trees and plants and eat less food that is manufactured in plants.

24. Drink green tea and plenty of water. Eat blueberries, broccoli, and almonds.

25. Try to make at least three people smile each day.

26. Don't waste your precious energy on gossip, energy vampires, issues of the past, negative thoughts or           things you cannot control. Instead invest your energy in the positive present moment.

27. Eat breakfast like a king, lunch like a prince and dinner like a college kid with a maxed out charge card.

28. Life isn't fair, but it's still good.

29. Life is too short to waste time hating anyone. Forgive them for everything!

30. Don't take yourself so seriously. No one else does.

31. You don't have to win every argument. Agree to disagree.

32. Make peace with your past so it won't spoil the present.

34. No one is in charge of your happiness except you.

35. Frame every so-called disaster with these words: 'In five years, will this matter?'

38. Time heals everything.

39. However good or bad a situation is, it will change.

40. Your job won't take care of you when you are sick. Your friends will. Stay in touch.

7 of the most fascinating and powerful materials science has come up with in recent years.

We often hear of new technological improvements - robots, gadgets, phones, vehicles, medicine and more. But these are just part of the picture of scientific achievement. No less important is the field of chemical engineering, which has invented some amazing materials in recent years, materials that may forever change our lives. 

1. Aerogel
Aerogel is the proud holder of 15 mentions in the Guinness Book of Records, which is more than any material has ever had. 
Also known as the 'frozen smoke', a nickname resulting looking like solid smoke, aerogel is actually 99.8% empty space, which explains its semi-transparent look. This material is a terrific insulator. 
With a shield made from aerogel, you could challenge any flamethrower without danger - it will take it without you feeling a thing. It does the same with cold. With enough of it, you could build a comfortable house on the moon. 
Another amazing factoid - an inch of aerogel could have an internal structure so complex that an inch long piece could have a surface area as long as football field. 
2. Carbon nanotubes

Imagine long chains of carbon, these super-structures are bonded together by the greatest power in all of the chemical world, the sp2 bond. These carbon nanotubes have been constructed with length-to-diameter ratio of up to 132,000,000:1, significantly larger than for any other material.
This means they are exceptionally strong, and in fact, may be the only material humanity will be able to use to construct the 'space elevator' that will cart people and cargo up and down from space stations hovering above the earth.
Carbon nanotubes are 300 times stronger than steel, meaning you could potentially build towers hundreds of kilometers tall (or thousands of feet).
3. Metamaterials

Metamaterials are artificial materials engineered to have properties that may not be found in nature. They are assemblies of multiple individual elements fashioned from conventional microscopic materials such as metals or plastics, but the materials are usually arranged in periodic patterns. Metamaterials gain their properties not from their composition, but from their exactingly-designed structures. Their precise shape, geometry, size, orientation and arrangement can affect the waves of light or sound in an unconventional manner, creating material properties which are unachievable with conventional materials.
These metamaterials achieve desired effects by incorporating structural elements of sub-wavelength sizes, i.e. features that are actually smaller than the wavelength of the waves they affect. The primary research in metamaterials investigates materials with negative refractive index. Negative refractive index materials appear to permit the creation of super lenses which can have a spatial resolution below that of the wavelength. In other words - it makes invisibility cloaks.
4. Nano-Diamond

Nanodiamond was convincingly demonstrated to be produced by compression of graphite in 2003 and in the same work found to be much harder than bulk diamond, which makes it the hardest known material, while also being incredibly strong, light, and made of the most common element you can find - carbon. It is an amazing heat conductor and has the highest melting point of all materials. Machines built with this material would be lighter, stronger and more powerful than anything we have today.
5. Amorphous metal


By cooling molten metal quickly before it has time to re-align its particles in a solid shape, we can created amorphous metals - metals that have a disorganized atomic structure. Due to this structure anomaly, they are twice as strong as steel, and a few armies are considering using them for shields. In addition to their strength, amorphous metals have improved electricity conductivity and can improve the efficiency of a power grid by up to 40%, saving a huge amount of energy and the burning of fossil fuels.
6. Transparent Alumina

This material is 3 times as strong as steel, while being transparent. There are so many applications for this that the mind boggles. Imagine buildings made of transparent, stronger steel. It will reduce visual pollution in the cities. Many structures that stand alone could be invisible (with just a little opaqueness so we know they are there of course).
7. E-textiles

In about 10 years, you and everyone you know will probably know all about E-textiles. In fact, you'll be covered with them.
Why carry our cell phones around when we can just wear them? Clothes in the future will be embedded with these tiny E-Textiles (already existing today) that can monitor our health, project videos, make phone calls and bring up information from the Internet when we need it. The possibilities are endless.
