From The Telegraph:

An 'optical computer' which uses light particles rather than traditional circuitry has performed the first ever calculation, as scientists hope it could pave the way for a computer smaller and faster than anything seen before.

Scientists have hailed the step, despite the calculation taking longer than a schoolchild.

The optical quantum chip uses single particles of "whizzing" light which could eventually pave the wave for a "super-powerful quantum computer".

Midway


the mighty midway in all its glory, originally uploaded by smcgee

I followed my three-step plan and I feel recharged now, ready for another week. This year was baby's first Minnesota State Fair. I got to see chickens and eat a lot, Jenna took Natalie on the carousel, and we all had a fun time.

Making a guitar is harder than I thought, so I started building a compost bin instead. Progress is moving along a little better on this project. If we end up staying until spring, I figured I might as well get some compost going for next year's garden.

Jenna accused me of never eating the carrots from our garden, so I dug up a bunch. We cooked them into a quite tasty soup. We pureed until it was totally smooth. This recipe is going into the permanent file.

The Singularity And The Fixed Point -- A Commentary

From Technology Review:

The importance of engineering motivation into intelligence.

Some futurists such as Ray Kurzweil have hypothesized that we will someday soon pass through a singularity--that is, a time period of rapid technological change beyond which we cannot envision the future of society. Most visions of this singularity focus on the creation of machines intelligent enough to devise machines even more intelligent than themselves, and so forth recursively, thus launching a positive feedback loop of intelligence amplification. It's an intriguing thought. (One of the first things I wanted to do when I got to MIT as an undergraduate was to build a robot scientist that could make discoveries faster and better than anyone else.) Even the CTO of Intel, Justin Rattner, has publicly speculated recently that we're well on our way to this singularity, and conferences like the Singularity Summit (at which I'll be speaking in October) are exploring how such transformations might take place.

New Microprocessor Runs On Thin Air



From The New Scientist:

There's no shortage of ways to perform calculations without a standard electronic computer. But the latest in a long lineMovie Camera of weird computers runs calculations on nothing more than air.

The complicated nest of channels and valves (see image) made by Minsoung Rhee and Mark Burns at the University of Michigan, Ann Arbor, processes binary signals by sucking air out of tubes to represent a 0, or letting it back in to represent a 1.

A chain of such 1s and 0s flows through the processor's channels, with pneumatic valves controlling the flow of the signals between channels.

Gandhi: A Greatness Defined

Greatness is achieved by making an exceptional contribution to humanity. Marie Curie (1867-1934), who founded modern oncology through her groundbreaking research on radioactivity, received two Nobel Prizes and rightfully remains one of the most celebrated women and individuals in recent history.
.
During the same era, an emaciated Indian man caught the attention of the world by forcing the mighty British Empire to evacuate much of South Asia without firing a single shot. Rather than being skilled in the art of scientific research, the greatness of Mohandas Gandhi (1869-1948) lied in his fearless quest for truth and justice. Through bold action and words of timeless compassion and wisdom, his life and legacy continues to inspire millions around the world to fight poverty, disease and ignorance.
.
Born in India in the same year that witnessed the completion of both the Suez Canal and the Transcontinental Railroad in America (1869), Gandhi had a wife by age 14 from an arranged marriage prior to setting out for England to study law at University College in London in 1888. Five years later in 1893, Gandhi relocated to South Africa and proceeded to take on the system of rigid discrimination against Indians by confronting the authorities directly. After being asked repeatedly to move to a third-class railroad car despite having a first-class ticket in one famous incident, he refused on principle and was promptly thrown off the train. By 1906, Gandhi had organized a political opposition party of Indians in South Africa committed to Satyagraha or non-violent protest to achieve its objective of an equitable society.
.
In 1915, Gandhi returned to India and employed the same non-violent political campaigns along with 'non-cooperation' to ultimately destroy the twisted ideological legitimacy of British colonial rule in India. By the time of his death at the hands of a Hindu radical on 30 January 1948, Gandhi had managed to accomplish with words and peaceful resistance what Hitler could not achieve with vast armies and destructive weaponry - a defeat of the British Empire.
.
On the way to creating an independent India, Gandhi maintained a rigorous schedule of spinning cloth, reading, writing and reflecting on the greater truths of life. At the same time, he did not shy away from constructively criticizing the West for being overly materialistic and prone to war. For those that listened then and still listen to his sage words through books, Gandhi had a unique ability to encapsulate truths and challenge long-held assumptions by men and women with a single insightful comment. A few of his more trenchant and well-known sayings appear below with analysis:
.
'Freedom is not worth having if it does not include the freedom to make mistakes'
.
Gandhi may have been deeply religious, but he never advocated a religious state. His views on state and society were between a type of federalism and anarchism. Gandhi rightly questioned the right of any state to impose punitive moral laws. On a personal level, people must allow others to make mistakes and live life - not to judge - but to forgive.
.
I object to violence because when it appears to do good, the good is only temporary, the evil it does is permanent'
.
Gandhi's non-violent campaigns against oppression inspired Martin Luther King Jr. to wage his successful campaign for civil rights with moral force or Satyagraha. Gandhi can also be credited with influencing French and other European activists in the 1960s. The above quote brings the second Iraq war (2003-present) and the ongoing war in Afghanistan to mind. Celebrations during the overthrow of Saddam Hussein and the Taliban have turned to frustration as these conflicts continue with no end to violence in sight. It is worth noting that Gandhi opposed the use of violence to remove Hitler from power in World War II, and he once suggested that European Jews commit mass suicide as a protest against Hitler. According to Gandhi, the Jews would have been acting out of 'true heroism'. In order to remain ideologically consistent in espousing non-violence, Gandhi drifted into irrational thought. He can be forgiven, however, because his views on the 'evils' of violence upon society and the individual have been proven correct. If nothing else, leaders of democratic nations must consider the larger and long-term consequences of projecting violence to achieve political objectives.
.
'When I despair, I remember that all through history the ways of truth and love have always won. There have been tyrants and murderers, and for a time they can seem invincible, but in the end they always fell. Think of it - always.'
.
No commentary can add to his view on the role of truth and love in human history. Just think of it - always.

Future Robot Soldiers?



The Exoskeleton: Extreme Technological Innovation -- Raytheon

Raytheon Company’s research facility in Salt Lake City, Utah, is developing a robotic suit for the soldier of tomorrow. The exoskeleton is essentially a wearable robot that amplifies its wearer’s strength, endurance and agility. Reminiscent of super heroes depicted in comic books and Hollywood movies, the bleeding edge technology effectively blurs the lines between science fiction and reality. So much so, that Popular Science magazine recently likened Raytheon’s exoskeleton to the “Iron Man”® depicted in the blockbuster movie of the same name.

From Popular Science:

While Hollywood focuses on robots several times taller than humans, some researchers are building tiny robots that could fit on your fingernail. These microbots would work in swarms to collect data for a variety of applications, such as surveillance, micromanufacturing, and medicine.

The researchers, from institutes in Sweden, Spain, Germany, Italy, and Switzerland, use a novel approach to allow robots to be built cheaply and in large quantities. Working on a limited budget, they built an entire robot on a single circuit board.

CANCEL


hold | cancel, originally uploaded by wootam!

If you've been following along, you know we are having trouble with the sale of our house. Ultimately we had to cancel the offer. Our appraisal was significantly lower than the agreed-upon purchase price, and our erstwhile buyer-hopefuls couldn't make up the difference.

We are fortunate in that we don't need to sell, so we can be picky. Rather than selling at a loss, we decided to keep our perfectly good home in the city (for now) while it goes back on the market. The whole thing bums me out.

On the positive side, it didn't take long to start getting requests for showings again. Maybe we'll sell it this year after all.

Return of the Seagull

Last week saw us back in Derby, this time painting the outside of the Children's Emergency Department. It was a little different for us, using the different paints, painting on a very bobbly wall and the use of a rather high scaffold, but still good fun!
Warren, Shrimpy, Puffball and Crabby help direct people in in their own unique way!

As well as the outside, we also did a little more work inside on a corridor that connects to the rest of the hospital. The brief for this was more seagulls, but to incorporate the other various wards we had to inclu

Lincoln On Entering College

Another school year is only hours away. At colleges around the world, freshmen are being dropped off on campuses to begin their final chapter before young adulthood. The next four years, considered by many graduates to be the best years of their lives, will require self-initiative, focus and the ability to withstand heavy doses of caffeine in order to 'pull all-nighters'. Of course, staying up all night to finish a paper or study for an exam implies a lack of self-initiative through the art of procrastination. Nevertheless, it is a higher education rite of passage.
.
University faculty members are also preparing for a year of new students and challenges in an era of budget shortfalls and declining enrollments in some cases. Rather than looking around the room in their 100 and 200 level classes to see who's there this semester, professors ought to take time to consider who is not there as well. Essentially, there are two groups of students that will not appear in the college classroom this fall. The first one is comprised of the failed applicants. Despite having above average grades and test scores, these young men and women were simply edged out by their peers. What will they do? Some will take a few classes over the year, perhaps at a community college, to bolster their academic resumes or retake standardized tests with the hope of earning a higher score. At the same time, they will work to save money for the burdensome costs of tuition and room and board.
.
In 1860, presidential candidate Abraham Lincoln took time out of his busy summer schedule to write a consoling and inspiring letter to the best friend of his son Robert. Both had applied to Harvard. Unlike Robert Lincoln, however, George Latham failed to gain admission. When the future president learned of George's rejection, he had an unusual visceral reaction. George, whose father had died some years earlier, was looked upon by Lincoln fondly as one of the family. Furthermore, Lincoln, who had less than a year of formal education himself, took the rejection to heart. On 22 July 1860, he expressed his thoughts in the following lines (edited):
.
My dear George,
.
I have scarcely felt greater pain in my life than on learning yesterday from Bob's letter, that you failed to enter Harvard. And yet there is very little in it, if you will allow no feeling discouragement to seize, and prey upon you. It is a certain truth, that you can enter, and graduate in, Harvard University; and having made the attempt, you must succeed in it. 'Must' is the word.
.
I know not how to aid you, save in the assurance of mature age, and much severe experience, that you cannot fail if you resolutely determine, that you will not.
.
In your temporary failure there is no evidence that you may not yet be a better scholar, and a more successful man in the great struggle for life, than many others, who have entered college more easily.
.
With more than a common interest I subscribe myself very truly your friend,
.
A. Lincoln
.
Lincoln's letter of encouragement to a student facing academic adversity has proven to be timeless. It should not only be read by those receiving rejection letters but also by undergraduate and graduate students alike in their quest to endure long days and sleepless nights of research and writing.
.
What about the second group of college hopefuls not in attendance this year? Rather than missing the cut from insufficient grades or lower test scores, they simply lack the means to finance a college education - and their numbers greatly eclipse the fortunate ones in class.
.
Hopefully, the next generation of college graduates will promote policies designed to reduce the large numbers of 'college-disappointed' men and women. Indeed, all hard-working high school graduates deserve an opportunity to pull an all-nighter.

3 New Farm Bots Programmed To Pick, Plant And Drive



From Popular Mechanics:

Intelligent, manned machines aren’t just for warplanes and border guards—they can be found on the farm too. Increasingly, agro-bots are taking laborious tasks out of the farmer’s helper’s hands, and saving time and money in the process. Here are three robotic farm servants who may right now be working in a field near you.

Agricultural robots are already among us: mowing grass, spraying pesticides and monitoring crops. For example, instead of regularly dousing an entire apple orchard with chemicals, towed sensors find diseases or parasites with infrared sensors and cameras, and spray only the affected trees. But could a robot wholly replace a migrant worker?

The Origin Of Computing

Holly Lindem (photoillustration); Gene Burkhardt (styling)

From Scientific American:

The information age began with the realization that machines could emulate the power of minds

In the standard story, the computer’s evolution has been brisk and short. It starts with the giant machines warehoused in World War II–era laboratories. Microchips shrink them onto desktops, Moore’s Law predicts how powerful they will become, and Microsoft capitalizes on the software. Eventually small, inexpensive devices appear that can trade stocks and beam video around the world. That is one way to approach the history of computing—the history of solid-state electronics in the past 60 years.

New Nanolaser Key To Future Optical Computers And Technologies

Researchers have created the tiniest laser since its invention nearly 50 years ago. Because the new device, called a "spaser," is the first of its kind to emit visible light, it represents a critical component for possible future technologies based on "nanophotonic" circuitry. The color diagram (a) shows the nanolaser's design: a gold core surrounded by a glasslike shell filled with green dye. Scanning electron microscope images (b and c) show that the gold core and the thickness of the silica shell were about 14 nanometers and 15 nanometers, respectively. A simulation of the SPASER (d) shows the device emitting visible light with a wavelength of 525 nanometers. (Credit: Birck Nanotechnology Center, Purdue University)

Cigar Box Guitar


Hobo Nickel Cigar Box Guitar, originally uploaded by Resist Banjo Works

We use hair bands tied around cupboard knobs to baby-proof the kitchen. Our daughter was pulling at them the other day, and she was delighted by the different plinking sounds she could make. I got the idea to build her some kind of instrument, and with the death of Les Paul fresh in my mind, I decided that my next project should be a simple 3-string cigar box guitar.

There are build plans all over the web. Here's a basic one, and a nicer one. As a general guide I'm starting with the detailed PDF instructions from Maker Workshop. There's another video by GeekDad, and for inspiration I'm looking at beautiful examples like the one above by Resist Banjo Works.

Menards had most of the supplies I needed (except the cigar box and a few little bits I can pick up at Ace). I also got a woodworking file to attempt basic shaping of the neck and headstock. I stood in the rasps and files aisle scratching my head until Natalie started to fuss, then I just grabbed the cheapest one and went home. I'll try to post notes as I go through this project. Wish me luck!
