On science literacy…

In this WIRED article, a scientifically illiterate writer explains "science literacy". It's as horrid as you'd expect. He preaches the Aristotelian version of science that Galileo proved wrong centuries ago. His thesis is that science isn't about knowing scientific facts, but being able to think scientifically. He then claims that thinking scientifically is all about building models of how the world works.

This is profoundly wrong. Science is about observation and experimental testing of theories.

For example, consider the following question. If you had two balls of the same size, one made of lead and the other made of wood, and you dropped them at the same time, which would hit the ground first (ignoring air resistance)? For thousands of years Aristotelian scientists claimed that heavier objects fell faster, purely by reasoning about the problem. It wasn't until the time of Galileo that scientists conducted the experiment and observed that these balls hit the ground at the same time. In other words, all objects fall at the same speed, regardless or size or weight (ignoring air resistance). Feathers fall as fast as lead on the moon. If you don't believe me, drop different objects from a building and observe for yourself.

The point here is Continue reading

Apple rewards CEO Tim Cook with $58M for bang-up job on Wall Street

Apple CEO Tim Cook earlier this week was awarded 560,000 shares, worth approximately $57.7 million, receiving the full amount of a grant due him because of Apple's performance on Wall Street over the last two years. As it did in 2014, Apple withheld just over half of the total shares -- 290,836, worth about $30 million on Monday -- for tax purposes. The half-million shares were this year's allotment under a revised schedule designed at Cook's request in 2013. Then, Apple's board modified the executive's vesting plan, which had set two large stock handouts for a massive 1 million-share grant -- after last year's stock split, equal to 7 million -- when Cook assumed the lead role at the Cupertino, Calif. company just weeks before co-founder Steve Jobs' death.To read this article in full or to leave a comment, please click here

No Jitter: Network Change: Evolutions and Revolutions
By Tom Noelle
Networking, and its transformation, is more than just technology. Broadband Internet came along during an unfortunate shift in the politics of networking. In the ’80s and ’90s we were moving from a global vision of communications as a regulated monopoly or even a government agency to one of a free market. The Internet exploded on the scene Continue reading

Wi-Fi blocking debate far from over

Following the FCC’s warning in January that it would no longer tolerate the Marriotts of the world blocking visitors’ WiFi hotspots, I set a reminder on my calendar to revisit the topic six months later. After all, the issue of WiFi blocking sparked strong reactions from IT pros, end users and vendors of wireless LAN products early in the year, and I figured it wasn’t over yet. So I started by making an inquiry directly to Marriott Global CIO Bruce Hoffmeister, who foisted me on to a company spokesman, who “respectfully declined” to connect me with anyone for an update on how Marriott is now dealing with perceived threats to its network. He simply directed me back to Marriott’s statement from January that it would behave itself, no doubt hoping the hotel chain could further distance itself from the $600K fine that the FCC hit it with, as well as the rest of the bad publicity. I also inquired at the FCC, which in Marriott-like fashion, referred me back to the agency’s last statement on the matter from January, and in a follow up, said it can’t comment on whether any new investigations are underway.

Researchers find many more modules of Regin spying tool

Security researchers from Symantec have identified 49 more modules of the sophisticated Regin cyberespionage platform that many believe is used by the U.S. National Security Agency and its close allies.This brings the total number of modules known so far to 75, each of them responsible for implementing specific functionality and giving attackers a lot of flexibility in how they exploit individual targets.Regin came to light in November last year, but it has been in use since at least 2008 and antivirus companies have known about it since 2013.To read this article in full or to leave a comment, please click here

QOTW: Height

Height is the measure of littleness. The man who has not the sense of true greatness is easily exultant or easily depressed, sometimes both together. It is because the ant does not consider the giant beetle that he looks down on the tiny gnat; and it is because the walker does not feel the wind from the heights that he lingers on the mountain slopes.
