The Scientist - Speaking of Science

Speaking of Science

How fleeting are the wishes and efforts of man! How short his time! and consequently how poor will be his results, compared with those accumulated by Nature during whole geological periods! Charles Darwin, On The Origin of Species (1859)

Why them? Why is this species [the New Caledonian crow] on a small island in the Pacific able to not just use but to manufacture a variety of tools, and in a flexible rather than a rote or programmatic way? Why are they able to do at least as well as chimpanzees on experiments of cognition…?

China's New Green Plan: the Local Angle





China's New Green Plan: the Local Angle


Posted Dec 8, 2010 by Warren Karlenzig

To get a better view of what was happening at the local level in terms of China's new national low carbon and ecological planning, I recently traveled to Jiaxing, Zhejiang Province. Jiaxing (above--click on photos for full size) is a "small town" of about four million that is now only 21 minutes (80 kilometers) from metro Shanghai on a new high-speed electric train line, the fastest in the world--the line, which will eventually extend to Beijing, recently set a test record of 259 miles per hour.

I was traveling with other strategic advisers from the Institute for Strategic Resilience, Irv Beiman and Daniel Zhu. Jiaxing is Zhu's hometown, and he helped arrange our two-day visit.

Jiaxing sees itself as a "Garden City" (with more than 40 percent forest cover), and truly it felt that way thanks to extensive landscaping and forests planted on the site of former rice fields. Jiaxing is also billing itself as the "Oriental Silicon Valley," which embodies China's plans to transform its economy, particularly in eastern coastal areas such as the Yangtze Delta, from manufacturing to service industries, such as IT and green technologies, to supplant its product-export-dominated industrial base.

Excellent post. China's commitment to reduce green house gases to avert climate change is a welcome sign for clean environment.

Chinese Army to Enlist 10,000 Pigeons and other Stories


Chinese Army to Enlist 10,000 Pigeons

From their humble beginnings along the rocky cliff sides of Africa and Asia some 20 million years ago, pigeons can now by found pretty much anywhere there´s a statue being erected or sandwich being eaten -- though long before we they were merely pests, they served a vital purpose that has evidently not been lost.

 It was recently revealed that China plans to increase its military spending 12.7 percent, but evidently not all that money will go towards tanks and fighter jets. According to China Central Television, the People's Liberation Army will soon be training 10,000 pigeons to act as couriers in the event that traditional communication equipment fails.

Humans first began domesticating pigeons around 5,000 to 10,000 years ago -- at first for food and to use their feathers, but later as carriers, taking advantage of their superb homing abilities to deliver messages over long distances. They were ideal couriers throughout the Ancient world, like in Greece where they reported the winners of the first Olympic Games.

INDIA GROWTH OF ENGINEERING AND TECHNOLOGY

INDIA GROWTH OF ENGINEERING AND TECHNOLOGY
Posted Date: 03 Jun 2008 | Author: b.thirumaya prabhu

Engineering education, unlike other types of professional education, has not had a long history. Though the ancients and medievals had built large brick and stone houses, castles, cities and huge temples, bad constructed long highways and aqueducts and dug canals, which show considerable knowledge of what are now earned civil and hydraulic engineering and of properties of building materials, this knowledge must have been derived empirically. Beginnings of mechanical engineering are to be found in the manufacture and use, of tools, means of transport, simple machinery like lathes, and weapons of offence and defense. Rudiments of chemical engineering are to be seen in the old metallurgical practices. But there were no organised schools for teaching apprentices the use of machinery or knowledge of processes; knowledge passed from generation to generation of craftsmen and artificers, by word of mouth, and was thus confined to castes and guilds. 

The Industrial Revolution With the advent of the Industrial Age, which was ushered in by the discovery of the steam engine by James Watt about 1780, and the ability to, generate and to handle large amounts of power rendered possible by the invention of the steam engine, men passed from dependence on human labour and hand tools to large and complicated machinery ; production of commodities passed from cottage workshops to factories. 

Transportation by bullock-carts, horse-driven carriages, and wind or man driven boats, gave way to railroads and steamships. All this necessitated the construction of large machines, engines, ships and carriages, and gave rise to problems of industrial finance and labour.

Early Engineering School in Europe-While inventive genius was called upon to devise new kinds of machines and to handle new types of processes, the craftsmen and artisans were called upon to put these designs into actual practice. They were asked to test and handle these machines and to repair them whenever necessary. The engineer was thus evolved from two different streams- first from the artisans and craftsmen on one side, who belonged to the lower orders of the less specialised society of the last century, and on the other side from the genteel class who had knowledge of sciences, and had acquired habits of disciplined and organised thinking.

We’re moving too slowly

We’re moving too slowly

Joydeep Gupta | February 25, 2011


Gro Harlem Brundtland – high priestess of sustainable development – tells Joydeep Gupta why progress towards a healthier, happier planet is still too slow, wrapping up our special series on well-being economics.



“The oil and coal lobby in the US is mostly responsible for creating the kind of atmosphere that has prevented progress. These big corporations are very powerful. I know this myself from working against the tobacco industry.”


Gro Harlem Brundtland is the high priestess of sustainable development. The former head of the World Health Organisation and Norway’s first – and so far only – female prime minister commands a level of respect around the world perhaps matched only by Nelson Mandela.


Not many remember that she is also a medical doctor with a degree in public health, and that it was from the health sector that she took the concept of well-being and applied it to planet Earth when she became the chair of the World Commission on Environment and Development in 1983.

New Compostable SunChips Bag Released

It’s always great to see a large company taking steps to reduce waste, which is why I’m very excited about the release of the new compostable SunChips bag.

Frito-Lay had high hopes when it first released the compostable SunChips bag last year, but one issue prevented the bag from being popular with consumers: its high level of noise. While customers loved that the bag was 100% biodegradable, it just didn’t seem to be worth the pain released on their eardrums. At one point, an Air Force Pilot even said that the bag created more noise than the cockpit of his jet.

Luckily, Frito-Lay listened to the complaints, putting engineers to work to create a newer version of the compostable bag that would be quieter than its noisy predecessor. They found that tweaking the adhesive holding the bag together - making it more rubbery - significantly reduced the bag’s noisiness.

A Hybrid Path to Feeding 9 Billion on a Still- Green Planet

A Hybrid Path to Feeding 9 Billion on a Still- Green Planet


By ANDREW C. REVKIN



Improvements in crop genetics and wasteful, inefficient farming and food management provide the biggest gains in a plan to triple agricultural production on today’s global farm acreage, with the potential shifts displayed above. This vision of a path to feeding roughly 9 billion people with rising living standards, while also limiting deforestation and other damage to ecosystems, comes from Jason Clay, a longtime analyst of the intersection of food and the environment and a senior vice president of the World Wildlife Fund.

Here’s his draft paper on this strategy. The genetic work he describes includes all uses of genetic research to improve plant productivity or farming efficiency. Genetic modification, the realm of the GMO’s that are anathema to some environmentalists and much of Europe, is a subset of that arena. [At the Climate, Mind and Behavior Conference of the Garrison Institute on Thursday, Clay laid out the logic behind working with big corporations to foster food production that can fit on a finite planet. He made a point that he stressed at the recent annual meeting of the American Association for the Advancement of science: "In the next 40 years we're going to have to produce as much food as was produced in last 8,000."]


Just how much power do we need anyway?


Just how much power do we need anyway?


We all know we need to get off fossil fuels and replace them with carbon-neutral alternatives. The question is not IF we should choose this path, but how best to get where we need to go. There are those who, fairly enough, worry that those clean renewables aren't up to the job. This is a critical question, because if renewables can't fill the void, then we are left with no option but to build more nuclear reactors, with all the myriad problems that accompany them, most notably price, which is forever rising. So much money is at stake that we need to sort out this question, soon.


All energy could be renewable by 2030


All energy could be renewable by 2030



Hopefully this news isn’t a big shock to anyone, but fossil fuels–which currently make up 80-percent of all the world’s energy supply—are running out, and at the current rate of consumption, the world will hit a cataclysmic energy crisis within most of our lifetimes. When that happens, the world will quickly fall apart, wars will be fought over the smallest surpluses, our technology will be pushed back centuries, dogs and cats will live together, etc., etc. In short, it would be bad. Very very bad.





But that doesn’t mean we should all begin stocking up on our ammo and sharpening our knives just yet. The grim future predicted by many, where even starting a gas guzzling V8 car would be ruinous to all but the richest people in the world, can be avoided, or at the very least slowed significantly.


A new study published in the Energy Policy Journal and recounted by Physorg.com, claims that with a concerted global effort, all energy could come from affordable and 100-percent renewable energy sources by the year 2030. We would also be able to continue to provide renewable and low pollution energy indefinitely.
