It’s been quite a while since I’ve read Dune. I found my way to this interesting conceptualization, Sietch Nevada, through my regular StumbleUpon clicking. For those not familiar with Dune by Frank Herbert, please check it out! It is an excellent novel, as described in my review. I find it interesting how many ideas are drawn from Sci-Fi. Everyday technology like cell phones, video conferencing, and robots (well maybe not everyday yet), were hinted to by authors long before they were developed. I find the Sietch concept intriguing because I lived in Phoenix, AZ for many years. A few years after I left, I started hearing about how Lake Powell, fed by the Colorado River, might dry up soon. I thought that it meant there would be no more water, but experts are referring to “dry” as unable to generate hydroelectric power. So, not only will water levels be low, but there could be power shortages as well!

A few years ago, the Science Channel aired an episode of SciFi Science, “How to Build a Lightsaber” hosted by theoretical physicist Dr. Michio Kaku. He explained some theories that might be used and developed a rough design that should be “workable in our lifetimes.” Of course almost all of his episodes end up with that qualification. Last month it looks like there was a breakthrough in the hardest part of making a lightsaber work, getting the blade to stop at a certain point.
Although the most prominent uses for controlling the depth of laser cutting are surgical and clinical, Fraser said the team is “very excited about the potential industrial applications,” especially since compared to clinics it’s easier to get new technology into industries.
Unfortunately, the goal is to make the lasers useful surgery, not chopping off alien arms at cantinas.

Happy Birthday Isaac AsimovHappy Birthday Isaac Asimov
Happy birthday Isaac Asimov! I started casually reading “In Memory Yet Green,” last month in my spare time. I would take it with me to places I expected to wait like the doctor’s office or something like that. It has been satisfying to finally get to know the author of my favorite science fiction series. According to this first volume of his autobiography, there is no real record of Isaac Asimov’s birthday. He was born in Petrovichi, Russia around 1920 and chose arbitrarily to celebrate his birthday on January 2nd.
Sadly, Isaac Asimov died of heart and kidney failure complications due to AIDS on April 6, 1992. He contracted HIV from a blood transfusion during a heart bypass operation in 1983. This link to HIV and AIDS wasn’t revealed until later when Janet Asimov published “It’s Been a Good Life,” in 2002.
It is a shame that such a talented author died before his time, but not before he wrote or edited over 400 books and countless essays and letters. I would have loved see how he continued his Robot and Foundation novels in the future. Hopefully I will find time to read some of his non-fiction this year, which most of his writing consists of. For a start, I received “Yours, Isaac Asimov: A Life in Letters,” for Christmas. I’m sure that it will be very interesting. If you haven’t read anything by Asimov, you should visit your local library or run a creative Google search. You’ll be in for a treat.
Blue Brain project combines neuroscience with computers to simulate brain activityBlue Brain project combines neuroscience with computers to simulate brain activity
Ever since I first read I, Robot by Isaac Asimov I have been interested in robotics and AI. Back in 1996 or so I had no idea that simulation of a brain might be possible in my lifetime. John Lehrer with Seed Magazine has written a very interesting article, “Out of the Blue“, which covers the Blue Brain project led by Henry Markram. One of the biggest challenges was determining how exactly a neuron is supposed to behave. Without that information, it would be impossible to simulate it. One of the freaky things about this project is that they have a robot conducting experiments and recording data 24/7. This robot is more efficient than 10 experienced lab technicians combined. I would assume that this robot only has enough programming to complete these experiments, but what if robots become sentient? What would keep them from creating other more capable robots? The current project aims to first simulate the brain of a 2 week old rat, which would then be transferred to a robot body to see how it develops.
With the current progression of technology, Markram suggests, “In ten years, this computer will be talking to us.” That seem a bit crazy, but who would have thought 10 years ago that there would technology capable of simulating 10,000 neurons and 30 million synaptic connections? That currently only represents a small slice of a 2 week old rat brain, but given how fast computing power is growing, I can’t see why Markram’s prediction would be impossible. If not 10 years from now, why not 20, or 30? I think that it is just a matter of time. I highly recommend reading the full article, especially if you have any interest in robotics or AI.
