Gorilla Glass and Google Glass

Gorilla Glass and Google Glass 1

Since I am an eyeglasses purveyor I thought I should write something about which I know a little. Mainly I’m aware of the optical properties of lenses in glasses but not so much the manufacturing of them. Interestingly, some lenses we call high index and recommend them for patients that have a high prescription. Using high index materials will make the lenses thinner but can slightly degrade the optical quality called Abbe value.

I need to get something out of the way first. Google Glass is not made of glass. Not even the little optical part that is the display. It’s all plastic with some titanium. But it’s a cool name. Eyeglasses aren’t really made of glass either these days (with some exceptions). But there still is a lot of glass around in our world. Some of it is made to be stronger and thinner which is why there is Gorilla Glass (for our smartphones and other electronic devices).

Gorilla Glass is made by Corning. They invented it over 50 years ago but called it Chemcor back then. Not a very catchy name for advertising which goes to show you how important a name is. Before explaining the gorilla part of glass, I should start off by saying that basic glass is made of heated sand (mainly). Additives like soda ash (sodium carbonate) make the process easier (lower heat required) and other additives like lanthanum oxide are used for eyeglasses lenses (glass lenses). Most glass like window glass can be classified as soda-lime glass.

Back to Gorilla Glass which your smartphone might have as the top layer that is touched (I’ll mention a few of the other brands later). It is chemically treated which means the glass is made and then put in a hot solution of potassium which allows the larger potassium molecules to seep into the glass. That packs the molecules closer together and makes the glass stronger and more scratch resistant. It protects the layers underneath and actually can be part (or most) of the devices structural support.

But just because our smartphone touch screens have this strengthened glass, they are still susceptible to cracking. Small scratches or even invisible cracking reduces the strength and makes each additional drop or scratch that much more likely to lead to a visible crack(s). When the force of impact overcomes the surface compression of the molecules that make up the glass, you’ve got yourself a visible crack. Dropping your phone or device on it’s corner focuses that impact in one place whereas dropping it flat might spread the force over a larger area and not cause a crack.

Now on to a few of the other glass materials that might be in your phone, or your next one:

Willow Glass – one of Corning’s newest materials that is very flexible and could wrap around your wrist

Gorilla Glass 2 and 3 – stronger and more scratch resistant, probably in the newest iphones.

Lotus Glass – another Corning product that could be used in LCD displays along with Gorilla Glass

Nippon Electric Glass – one of their products only reflects 0.08% of the light which they say is practically invisible (usually plastic and glass reflect between 8% to almost 15% of light)

Samsung – Youm is a new flexible display that can wrap around like Willow Glass

Dragontrail – yes, there’s a marketing name

This glass stuff is a multibillion dollar industry and you know who’s helping all this innovation? You and I are by buying these electronic gadgets. I am up for a new iPad Air. I don’t know who manufactured the glass in those since Apple tries to keep secrets but I bet it’s Gorilla Glass. If you do break your screen there are DYI videos on how to replace them which might be much cheaper than paying someone else to fix it…that is, if you dare try yourself (it’s really not that difficult).

Here’s a youtube video about the very flexible Willow Glass….

What color is caffeine?

What color is caffeine? 0

Pure caffeine is white. That coffee bean (really seed) that makes your coffee is brown because of roasting. The seed, before harvesting from the coffee tree, is generally green and the apparent function of caffeine in the seed acts as a natural pesticide. We don’t think of caffeine in our coffee as a pesticide but it just works that way for the seed. Insects don’t like caffeine. Ever see them drinking your coffee?

I drank coffee as a kid (and still do). I don’t remember how old I was when I started doing that but I remember adding lots of sugar and milk. Tasty. One day in college (that was a long time ago) after trying some No Doz I began to wonder if caffeine was good or bad. I did some real “research” (for me back then it was opening a book) at the library. This was before anyone had heard of an internet. I wasn’t able to decipher the chemical molecular structure but I didn’t read that caffeine was dangerous (in normal dosing). So I kept taking No Doz. I was proud that I sorta determined some background on this stuff.

There are a lot of known knowns and maybe as many unknowns about caffeine and it doesn’t affect everyone the same. Some genetic studies have found that a certain dose for some might increase nonfatal heart attacks. That would be about 3 cups or more. Those people are the slow metabolizers. Slow, as in slow caffeine metabolizing. It’s your liver enzymes that do this. They either function well at breaking down that caffeine molecule or they are not so hot at it. Regardless, every regular caffeine customer develops a certain tolerance. Adenosine receptors in your brain are the arbitrators of your habit.

What I really want to do is save everyone a lot of money and perhaps reduce some caloric intake at the same time. Now that I think about it. I want to reduce coffee spills, carbon footprints, coffee breath, yellow teeth and all this worry about coffee farmers and how they were paid. If you buy energy drinks, supplements or coffee creations from coffee shops, buy some caffeine pills instead. Someone get me some recipes for caffeine too. I couldn’t find anything interesting in my short google search. Buy store brand caffeine pills and break the big ones in half. You can get your five hour jones for less than 10┬ácents! I don’t mind the yellow color of the tablet either.
