One of the issues is that Dr Callendar has is a fear of Math and equations in popular reading. A lot of other people are afraid of these few very pretty symbols. Lets do an experiment and see if using some equations and symbols drives readers into fits of terror and prevents their understanding as they cower shivering under their chairs.
The below is from Heinz Pagels in the Cosmic Code (available on Kindle from Amazon and Nook from B&N for about 10 bucks). It shows up on Google books too. Go look, it's fun.
One part of the Uncertainty Principal is (p)x(q)h – where p and q (the is pronounced delta, e.g., delta-p) are the sums of all of the uncertainties — or differences — in a huge pile of measurements of the position and velocity of some particle we're measuring – and h is the tiny, but still not zero, number called the Plank constant. The mathematical symbols haven't changed meaning, so if h ain't zero, neither p or q can be either. We can be as precise as we like, until we hit the Plank Constant. This is not some mathematical oddity, it is how the universe operates. That is weird, and that is one example of quantum weirdness.
The question for the experiment is: Would Dr Callendar have done better to use the equation in the first article instead of metaphors from TV and Movies? Or, did they so frighten you that you need a good stiff brandy and a foot rub.
So I'm asking the same question to everyone on Slashdot. Would Dr Callendar been better off just diving in and dealing with Heisenberg and quantum mechanics using the tools that were developed for it.
Even casual users find typing faster than mousing. So while there are modes of interaction where it’s nice to sit back and drive around with the mouse, we observe people staying more engaged and more focused on their task when they can keep their hands on the keyboard all the time. Hotkeys are a sort of mental gymnastics, the HUD is a continuation of mental flow.
It’s smart, because it can do things like fuzzy matching, and it can learn what you usually do so it can prioritise the things you use often. It covers the focused app (because that’s where you probably want to act) as well as system functionality; you can change IM state, or go offline in Skype, all through the HUD, without changing focus, because those apps all talk to the indicator system. When you’ve been using it for a little while it seems like it’s reading your mind, in a good way.
