Apple has invented a new kind of gold (AAPL)

On Monday, Apple is finally going to tell us a lot more about the long-anticipated Apple Watch. Namely: how much it costs.

Predictions for the price of the coveted gold "Edition" version of the Apple Watch are ranging as high as $10,000 (or even higher!) — but there are suggestions it could cost significantly less. Why? Because, as Dr. Drang points out on Leancrew, Apple says it has invented a new kind of gold.

We know the watch is going to be 18-karat gold. But 18K gold isn't pure gold — it's an alloy of three parts gold to one part other material.

What Apple has done is produce a new patented alloy that contains less gold per volume while retaining the same 3:1 ratio and 18K classification. The other material isn't one of the standard metals used in alloys; it's ceramic, which is less dense. Dr. Drang on Leancrew explains this in more detail (emphasis ours):

How can this be? It’s because Apple's gold is a metal matrix composite, not a standard alloy. Instead of mixing the gold with silver, copper, or other metals to make it harder, Apple is mixing it with low-density ceramic particles. The ceramic makes Apple's gold harder and more scratch-resistant — which Tim Cook touted during the September announcement — and it also makes it less dense overall.

As developer Marco Arment points out on his blog, this reduced gold content opens the door ! to a sig nificantly cheaper Apple Watch Edition than people are speculating. "The uncomfortable issue of an extremely expensive watch that's completely obsolete in a few years would all be significantly less problematic if the Edition was priced closer to $2,000-$3,000," he writes. "We don't know yet if Apple will do that, but it sure looks like they can."

Apple design chief Jony Ive also talked about Apple's special gold in a recent profile in the Financial Times. He explained how Apple's new gold methods made it "twice as hard as standard gold."

This simple flow chart illustrates how low oil prices seep through the global economy (USO, OIL)

Some analysts have described the oil crash of late 2014 as the most important economic event since the financial crisis.

In February, Citi's Ed Morse said West Texas Intermediate crude oil prices could fall as low as $20 per barrel from its triple-digit level we saw last summer.

To help us understand how all this fits into the big picture, Morse's team offers this flowchart that shows all the effects that low oil prices continue to have on the global economy.

'Minecraft' no longer risks opening a big security hole on your PC

A castle in Minecraft

As a matter of course, Minecraft has required that you install Java's run-anywhere code base -- a big problem when that tends to introduce security exploits and annoying adware. However, the construction game should be considerably safer thanks to a low-key update in recent weeks. The Windows edition of Minecraft (OS X is coming later this year) now installs a standalone version of Java that's used only while you're playing. If you want, you can scrub the full version of Java without losing access to your blocky masterpieces. And the kicker? If you haven't been keeping on top of your software updates, the game may run smoother at the same time. It's not urgent that you get the upgrade, but it's definitely worth considering if you only bother with Java for the sake of living in Mojang's virtual world.
