From the Editor's Computer
By chance, the other day, I read a blurb about a 3D printer that is now available for home usage. Granted the price tag is still pretty high (roughly $30,000), thus prohibiting every household to have one. Never fear though, the price is dropping, as it tends to do with most electronic and computer related products.
Currently, 3D printers are predominantly marketed to businesses as a way of creating affordable scale models and prototypes of new products without having to hire outside companies and wait days. The ease of use allows anyone with computer skill to use it. Within hours, or even minutes, a company could “print out” their prototype and start testing and tweaking it. The process would not only save money for the company, it would also save valuable time and allow new products to be available to consumers sooner.
The most common 3D printers - according to the blurb I read - have a laser that turns a powder or a liquid polymer into a hard plastic. The finished product can be any shape at all.
By using any 3D creation program (i.e. a CAD program) or even a 3D representation of an object in a computer file, the printer is able to manufacture that object into a solid item.
While it may seem a little out of this world, how many things in our world - that were once only the stuff of science fiction books and movies - are now mainstream? Computers and phones are now small enough to carry in our pockets. A few years ago, we’d have laughed that such things were possible.
Though 3D printers are certainly not mainstream yet, the possibilities for future application are incredible, especially if the printers are able to handle a variety of materials besides plastic. For example, a 3D printer could open up the world of art and sculpture to the average person as they produce a design of 3D form on the computer, which is then reproduced. Need a spare part, just open the online manual and print it off. Or maybe you will order a piece of clothing, a kitchen appliance, or a car online, download a special computer file, and then “print” your new purchase in the comfort of your home without having to worry about shipping costs.
Lately I have been experiencing a different relationship with time. While the first month of the year seemed to whiz by so fast, individual days are not speeding by as fast.
Part of the reason for this strange phenomenon is that my watch stopped working three weeks ago and I’ve been watchless ever since. That is the longest I’ve even been without a watch. In fact, I usually feel incomplete if I don’t have a watch on my wrist to look at all the time.
While I don’t have a watch, I have access to a number of clocks at any given time - on my computer, my cell phone, on my desk, on the wall, in my car and watches on other people’s wrists. So I still know what time it is.
Without a watch to let me know how fast the minutes are winging by, I have noticed that they don’t fly by quite so fast. It seems I am able to get more done, and with much less rush.
Our perception of time truly is elastic, as it stretches and shrinks depending on what we are involved in, and whether we are thinking of the past, present or future.
I was having a good time
and the hours flew by.
I was bored and time dragged.
I was on a tight deadline
and time was running out.
The beauty of the mountains
was so breathtaking that time stood still. – Deepak Chopra
