Link When Charles Darwin, FRS,(12 February 1809 – 19 April 1882) hesitated to publish: "On the Origins of Species "(1859)

Science and scientists in Victorian and Edwardian literary novels: insights into the emergence of a new profession, Public Understand. Sci. 16 (2007) 205–222 comes as good reminder of, who the authors of the time were, and, of their efforts and those of the literary world to bring Science to the wider Public.

Correction to first post ref sidewiki in footnote refs.

"On the Origin of Species proved unexpectedly popular, with the entire stock of 1,250 copies oversubscribed when it went on sale to booksellers on 22 November 1859.[107] In the book, Darwin set out “one long argument” of detailed observations, inferences and consideration of anticipated objections.[108] His only allusion to human evolution was the understatement that “light will be thrown on the origin of man and his history”.[109] His theory is simply stated in the introduction: refs 107,108, 109 refer to an extensive account in Wikipedia.

As many more individuals of each species are born than can possibly survive; and as, consequently, there is a frequently recurring struggle for existence, it follows that any being, if it vary however slightly in any manner profitable to itself, under the complex and sometimes varying conditions of life, will have a better chance of surviving, and thus be naturally selected. From the strong principle of inheritance, any selected variety will tend to propagate its new and modified form.[110]

Darwin put a strong case for common descent, but avoided the then controversial term “evolution”, and at the end of the book concluded that;

There is grandeur in this view of life, with its several powers, having been originally breathed into a few forms or into one; and that, whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been, and are being, evolved.[111 in wikipedia]

Comment: how from mouth to ear from web error-deformation to web error the facts and perhaps the truth can be deformed, or even manipulated! cf. my sidewiki above, -insufficiently researched, and much confusion over Darwin's story eg. obvious errors in dates also found in the following link, not the best way to defend against censorship!

What all scientists and policy makers must contend with-Science Communication-Public Understanding...of Science

"The public reception of scientific ideas depends largely on two factors: people's ability to grasp factual information and the cultural lens through which that information is filtered. The former is what scientists tend to focus on when they give popular accounts of issues such as climate change. The assumption is that if they explain things very, very clearly, everyone will understand. Unfortunately, this is an uphill battle. The general public's average capacity to weigh facts and numbers is notoriously poor — although there is encouraging evidence that probabilistic reasoning can be improved by targeted education early in life" is Natures Editorial line. It continues

"Even more crucial, however, are the effects of the cultural lens."

The classical case of Darwin is summarized with talent. The negative reaction of the Church in England, is compared to the more positive welcome by much of the "3rd World" at the time, hoping to "improve their lot" embraced the theory, In China, Darwin's ideas were seen as supporting Confucians' belief in the perfectibility of the cosmic order. Latin American and Russian reaction figure in this enlightening Editorial.

"The lesson for today's scientists and policy-makers is simple: they cannot assume that a public presented with 'the facts' will come to the same conclusion as themselves. They must take value systems, cultural backdrops and local knowledge gaps into account and frame their arguments accordingly."
[As yet another international round cop15 is about to start Dec 7-18, 2009]
Nature's Editors warn:
The lesson for today's scientists and policy-makers is simple: they cannot assume that a public presented with 'the facts' will come to the same conclusion as themselves. They must take value systems, cultural backdrops and local knowledge gaps into account and frame their arguments accordingly. Such approaches will be crucial in facing current global challenges, from recessions to pandemics and climate change. These issues will be perceived and dealt with differently by different nations — not because they misunderstand, but because their understanding is in part locally dependent.

The Editorial concludes:
"Darwin once said: "But then with me the horrid doubt always arises whether the convictions of man's mind, which has been developed from the mind of the lower animals, are of any value or at all trustworthy." Researchers and policy-makers would do well to mimic his humility when presenting science, and remember how people's minds truly work."

And what of Shakespeare's quote This above all -to thine own self be true, And it must follow, as the night, the day, Thou cans't not then be false to any man.»?

Materials Science, Non Destructive Testing, NDT using Microwaves with PC laptop imagery, News 26Oct 09 from Missouri University of Science and Technology (MST) could help the Medical Practitioner detect cancer or burns

Missouri University of Science and Technology (MST) has developed a handheld camera that uses microwave signals to non-destructively peek inside materials and structures in real time.

The compact system can produce synthetically focused images of objects - at different planes in front of the camera - at speeds of up to 30 images per second. A laptop computer then collects the signal and displays the image in real-time for review. The entire system, powered by a battery similar to the size used in laptops, can run for several hours, rendering it portable.

"In the not-so-distant future, the technology may be customized to address many critical inspection needs, including detecting defects in thermal insulating materials that are found in spacecraft heat insulating foam and tiles, space habitat structures, aircraft radomes and composite-strengthened concrete bridge members," says Dr. Reza Zoughi, the Schlumberger Distinguished Professor of Electrical Engineering at Missouri S&T, who is leading the research effort.

The team believe that their work could help medical professionals detect and monitor a variety of skin conditions in humans, including cancer and burns, security personnel could detect concealed contraband (such as weapons) or again home owners could detect termite damage.

The idea for developing a real-time, portable camera came to Zoughi in 1998 while he was on sabbatical in France. In 2007, Zoughi's research group completed the first prototype and has spent the past two years increasing its size and overall efficiency.

"Unlike X-rays, microwaves are non-ionizing and may cause some heating effect," Zoughi says. "However, the high sensitivity and other characteristics of this camera enables it to operate at a low-power level."

Video:The Late Paul Caseaux looks at Projected Transportation Increases

Just Added to my Video Wall. More differentied support for R&D, 1.Business and Commerce Schools and Unversities 2) Physical Sciences and Engineering. Comments on what follows most welcome:

The video is in French so mono-linguists must trust my interpretation. Here,
the late Paul Caseaux looks at major issues involved with expected increases in Transportation. As usual his high quality mind extracts the essentials in the relative short term (next 20y).
He differentiates Freight from Travel, Local (France no, increase) from International (8% increase). He considers a 2x increase in Freight over the next 20 a good guess. Freight therefore is an international affair and involves the full production-logistics-distribution system of International (Global) Commerce. As such any research and development to master the trend in the current state of affairs [Climate-Change, Emissions reduction...) must be given to The Schools of Commerce and Universities in the field whereas, Travel (the lions share he admits) is much more a question of fashion and although there are commercial aspects Caseaux considers that in public travel most advances via research and development are predominantly of an engineering nature he says with a slight smile)
NB.The late P.Caseaux (1935-9Aug.2009) was a influential member of the French Académie des Technologies.
He personally after a conference at our Bar-des-Sciences in Nevers gave a very clear description of the Current Climate=Energy dilemma, and pointed me, in his opinion, to the most advanced French worker in the field, fellow Polytechnicien, Jean-Marc Jancovici whose work has been the focus of several posts throughout my pages.

Packaging Materials Selector aids decision-making and change, just the infamous Plastic bag syndrome or a serious step in the proper direction?

I was awakened to the subject as a whole not just the plastic bag rubbish, which incidentally allowed me to freely recycle garbade to the incinerator, I trust rather than to landfil.(I was told the landfills are rolled hence there is no biodegradability worth the name. Now I pay for a similar product or use one which has no recycleability control

Intelligence and food to spur Innovations and Innovators

I returned with pleasure to Dave MacKay's blog where almost all his posts are highly pertinent for all, either those wishing to map their professional activity or simply wishing to gen-up on current Climate Change, GW-global warming and energy issues, hopefully all of us. In his post pre-review of the book Challenged by Carbon by Brian Lovell, the blog reader's attention is drawn to the fact that "55 million years ago, an enormous global warming event, raising the temperature of the water at the bottom of the ocean by more than 4 degrees C within roughly 10,000 years occurred". I did a rapid Google search and invite readers to do the same.

There is a short history of the big oil companies attitudes from "believing what the rocks say" and they say there is a problem and the business as usual approach and "as a backdrop the war in Iraq

"Yes, some oil companies greened up their public facades in 2003, but have they reverted to business as usual behind the scenes? But what about the rest of the oil industry?"

Quoting MacKay's selection from Lovell since this cannot be over-echoed I believe: "In the second half of the book, Lovell indicates how he hopes the drama will unfold: "government intervention is essential" in relation to the transition to the low-carbon economy; "concerted action" is required from all oil companies; oil companies [and the coal mining and power gen lobby] should turn their remarkable technical skills to a new waste management business: capturing and storing carbon[dioxide CO2], especially carbon [CO2] from coal power stations.

MacKay's figures: "key numbers for carbon capture. A standard unit of carbon capture and storage is "the Sleipner""

1. Norway's implementation of a carbon-emission tax of $55 per tonne of CO2 (which can be compared to today's EU market price of 14.10 euros per tonne),

2. StatoilHydro is storing 1 Mt CO2 per year in the Utsira saline aquifer under the North Sea.

3. A 1-GW coal power station, running all the time, produces roughly 7 Mt CO2 per year. So every 1-GW power station would require roughly 7 Sleipners.

4. The cost to the consumer for electricity from that source might be in the ballpark of an extra 4p per kWh of electricity (similar to the present subsidy for wind power in the UK).

5. The scale of the waste to be stored is worth mentioning. The volume of 7 Mt CO2 (the approximate annual waste from 1 GW coal power station), after it's been compressed to the same density as water, is three times the volume of the great pyramid at Giza.

Looking for a field to research, choose the people to follw: Royal Society 2010 Anniversary Professorships

N°1 for materials science and engineering or materials chemistry could be Andre Geim FRS, FinstP who is Langworthy Professor of Physics at the University of Manchester and is known primarily for the discovery of graphene. Graphene is a single layer of carbon atoms densely packed into a honeycomb lattice and the first representative of one atom thick materials which until 2004 had remained unknown. Graphene has many potential uses ranging from ultrafast transistors to bendable gadgets and from composite materials to novel batteries, and has been tipped as a likely successor to silicon in electronics. Geim is also known for his educational experiments on magnetic levitation (the "flying frog" experiment) and the development of a biomimetic adhesive known as "gecko tape".

2. The current hotest of topics is undoubtedly Climate Change. The professorship goes to Professor Andrew Watson FRS, University of East Anglia. He aims to improve our understanding of carbon sinks' and develop a model for the global accounting of the atmospheric CO2 budget. I intend to put more RS top quality studies on climate chage etc. in further wikis and on my blogs.

Bioactive Glasses, Steel Slags, Glasses and Ceramics from waste


The impressive Sage Publication catalogue, currently freely available online, encouraged me to scan widely.

In the previous post, I naturally started to focus my scan on their materials science and engineering offer. (again) Not surprisingly, I stopped-off at the J. of Biomaterials Applications, where I learned of the field of Bioactive Glasses whose chemical compositions reminded me to some extent of earlier work previously encountered in Steelmaking R&D and byproduct valorisation (as early as 1970)

There is nothing like doing a little brainstorming to clear the mind. Since I am "no longer "in the box" so to speak, I found it is easy to think "outside the box" for what it's worth! I made a hazardous suggestion that one could possibly seek synergies between the high value potential of bioactive glasses eg. previous post, and glasses and ceramics obtained from steelmaking slag.

Now as a member of The Institute (IMM3) prudence and loyalty, not to mention privileged member access to The Institute catalogue (more than 20 peer reviewed materials dedicated journals, leads me to take a new look at these fields. I did not have to look far.
From the first on The Institute list "Advances in Applied Ceramics I found a Special Issue on Bio-ceramics for Tissue and Bone Engineering and Drug delivery, Jan 2009. It's editorial was entitled "Glasses and ceramics from waste" My suggestion appears still far reached, cf. quote from the guests editors, P.Colombo, Univ of Padova, Italy, A.R. Boccachini and Bill Lee both of IC London,UK London
"Considerable research effort has been expended in the last 30 years concerning the production of glasses and glass-ceramics from a variety of silicate wastes including coal combustion ash, mud from zinc metal hydrometallurgy, slag from steel production, ash and slag from waste incinerators, red mud from alumina production, electric-arc furnace dust, foundry sands as well as glass cullet and various waste mixtures. Vitrification is typically used to transform hazardous residues into inert slags, with significant advantages in terms of reduction in the volume occupied by the residue, as well as in the immobilisation of harmful pollutants within a chemically-durable inorganic matrix. The vitrified material, which can often contain complex crystalline phases, can then either be land-filled
or be used as the raw material for other products."

Choke or take a breath of fresh air!
Not quite the bioactivity sought in medical circles, I can easily imagine.

Then high endeavour, breaking fundamental and applied barriers to progress is what research is all about, I believe?

Of course as a lifelong member, I make frequent use and reference to this attractive and well presented site. Further I delve deeply into it's member resources, in particular to it's peer reviewd journals, perhaps more so as an "off-shore metallurgist, materials scientist and engineer in a relatively remote location.

I have a second reason to make this entry. I was thoroughly enjoying using Google's Sidewiki for my blog and sharing views on my first experiences yesterday 12 Oct.09 with ease and fluency biefly reviewing pubished journal materials, when I hit a snag apparently specific to IOM3 journals secured site. Very pleased with my prose, on Bioactive Glasses and Steelmaking Slag Valorisation. I now appear to have lost the full text! So a word of caution to new reviewers and sharers, take care to back-up your text. Cheers and good luck.
