Corning Reveals Gorilla Glass 4, Promises No More Broken IPhones

An anonymous reader writes "Corning introduced next-generation Gorilla Glass, which it said is ten times tougher than any competitive cover glass now in the market. The company says that the Gorilla Glass 4 so launched is to address the No.1 problem among the smartphones users- screen breakage due to everyday drops."

"Two" times, not ten times

[Anonymous Coward]

The article says "two times tougher than any competitive cover glass now in the market". The post reads "ten".

Not only that but what's "tougher"? Elastic Modulus? Ductility? Fatigue Limit? Tensile Strength?

News for nerds, remember? Ten is simply the base-2 representation of the same number that two represents in base-10. It's exactly the same statement.

Toughness is a perfectly good engineering term with a defined meaning. Look it up. Wikipedia is a decent start. "In materials science and metallurgy, toughness is the ability of a material to absorb energy and plastically deform without fracturing."

It's typically measured by an impact test.

Actually, even the Wikpedia article you linked gives multiple definitions for toughness, depending on application. Which one is used here remains poorly specified and opens up the possibility of ambiguous marketing platitudes. Now, if they said shear strength was improved overall by a certain percentage, that would be information.

Re:So is it two or ten times tougher?

One is in base 10, the other in base 2.

Now I can upgrade to the next iPhone.

Then when they announce Gorilla Glass x+1 I can upgrade to the next iPhone!

and Repeat...

News just in! Products get better incrementally, somehow only controversial when Apple does it. Film at 11.

Re:So, it is hard and flexible?

Please tell us how they achieved this feat or materials engineering.

Oh you silly slashdotter. Sure, you may have studied materials science and engineering, but do you have the real world experience? In the modern corporation it's all about teamwork. Well-managed teams can do more than any one person possibly could. In this case, the engineers make the glass hard. Then marketing adds the flexibility. See? Teamwork. Oh yeah, and management makes it all happen and does extra janatorial tasks like mopping up the excess bucks.

(Actually, cynicism aside, it's simply that hardness and flexibility are orthogonal axes in materials science).

Why not polycarbonate?

It works for my glasses well enough.

Re:No more broken iPhones..

"UP TO two times tougher than competitive glass" "survives drops UP TO 80 percent of the time"

Just meaningless weasel words.

It's not meaningless at all. It means exactly what it says: The glass is somewhere between negative infinity times and 2 times tougher than competitive glass. And it survives drops somewhere between 0 percent and 80 percent of the time.
So be sure and take those figures into consideration when considering buying the product.

Sorry to disappoint you, but everybody knows that Slashdot has exactly 8 actual users, 3,564,372 sockpuppet accounts, and an AI at the U of Illinois Champaign/Urbana that makes all of the AC posts as a way to blow off steam after dealing with grad students all day.
