May I comment on how much I love this board. Clearly I'm not the smartest person in the world, so I like to ask questions and propose certain things that I know are probably flawed and incorrect to a degree. Any other board in which I ask or state something disagreeable, would inevitably end up with a flood of insensitive, sometimes incoherent garbage. I don't mind being wrong and I don't mind being corrected. This is how I learn. However, why must people on 4chan be so negative about it, as if they are intentionally trying to incite feelings of belittlement. On this board however, I can obtain criticism in a much more constructive manner. I just wish more people were actively involved. Can we somehow promote this site and still maintain this level of civility?

Thanks for listening, as a reward I give you... A puffer fish.

This site was advertised on 4chan's /sci/, which is how I got here. There aren't many mathnerds here, which isn't surprising since 4chan got latex working.

I'll be heading to college in the fall as a freshman and I am majoring in chemical engineering. I've always had an interest in science, specifically molecular and cellular biology. I don't have much of a chemistry background (only took a semester in highschool) but chemicall engineering seems to have applications in the biotech industry.

I'm also very interested in space, specifically searching for life on other planets.

I've come here to ask, am I taking the wrong major? My college offers a minor in biochemical engineering, and I figure that will give me more of a biology background. Basically though, when I think of a chemical engineer, I think of someone making plastics...which I don't want to do.

Any chem engineers out there? Care to share your current experiences?

My advice is this, if you are really 1000% into a particular subject and you like to study it on your own, don't expect the related undergraduate coursework at a university (even Harvard) to impress you, because you probably know most of the material already. College is another hoop they make you go through before they'll hire you, basically, but if you go above and beyond and make use of campus resources in your free time purely for your own interest (the library for example) then it will not be quite so bad. Like, think of Good Will Hunting, do you think he learned his shit in classrooms? No, he went out on his own and read up for his own sake in his own free time, etc.

Your other option is to go to a bunch of parties and bone some drunk chick as she throws up, which isn't quite as bad as it sounds.

We are living in a Simulation

The Simulation Hypothesis proposes that reality is in fact a simulation of which those affected by the simulants are generally unaware. The hypothesis does not have global scope since, if true, it entails that there is a reality that is not a simulation as there must be a place housing the machinery on which the simulation is being run. The hypothesis itself relies on the development of simulated reality.

Forsyth Scientists Suggest Linkages between Obesity and Oral Bacterial Infection Anonymous 07/8/2009(Fri)04:51:50 No.203016

[Reply]

A scientific team from The Forsyth Institute has discovered new links between certain oral bacteria and obesity. In a recent study, the researchers demonstrated that the salivary bacterial composition of overweight women differs from non-overweight women. This preliminary work may provide clues to interactions between oral bacteria and the pathology of obesity. This research may help investigators learn new avenues for fighting the obesity epidemic.

This work will be published in the Journal of Dental Research, and is available online today at http://jdr.sagepub.com/cgi/content/full/88/6/519.�There has been a world-wide explosion of obesity, with many contributing factors,� said Dr. J. Max Goodson, senior author of the study. �However, the inflammatory nature of the disease is also recognized. This led me to question potential unknown contributing causes of obesity. Could it be an epidemic involving an infectious agent?� �It is exciting to image the possibilities if oral bacteria ar

In order to measure the salivary bacterial populations of overweight women, samples were collected from 313 women with a body mass index between 27 and 32 (classifying them as overweight). Using DNA analysis, the researchers measured the bacterial populations of this group and compared it with historical data from 232 individuals that were not overweight. Significant differences in seven of the 40 species studied occurred in the salivary bacteria of subjects in the overweight group. In addition, more than 98 percent of the overweight women could be identified by the presence of a single bacterial species, called Selenomanas noxia, at levels greater than 1.05 percent of the total salivary bacteria. These data suggest that the composition of salivary bacteria changes in overweight women. It seems likely that these bacterial species could serve as indicators of a developing overweight condition and possibly be related to the underlying causation.

Anonymous 07/8/2009(Fri)04:58:53 No.203021

Dr. Goodson noted that the reasons for a relationship between obesity and oral bacteria are likely complex. The observed relationship may be circumstantial as being related to diet or opportunistic due to metabolic changes. In the next phase of this research, Dr. Goodson plans to further examine this relationship by initially conducting a controlled cohort study to see if this initial observation can be reproduced. In addition, he hopes to conduct longitudinal studies in children to see if oral infection relates to weight gain. Ultimately, the development of strategies to eliminate specific oral bacteria would be required to provide definitive evidence that certain oral bacteria may be responsible for weight gain.

J. Max Goodson, DDS, PhD, is a Senior Member of the Staff at The Forsyth Institute and heads up The Forsyth Clinical Research Collaborative (CRC). . Principal research personnel associated with the CRC include scientists that conduct clinical and health care delivery research.

Holy shit! Swearing relieves your pain!

"Although a common pain response, whether swearing alters individuals' experience of pain has not been investigated. This study investigated whether swearing affects cold-pressor pain tolerance (the ability to withstand immersing the hand in icy water), pain perception and heart rate. In a repeated measures design, pain outcomes were assessed in participants asked to repeat a swear word versus a neutral word. In addition, sex differences and the roles of pain catastrophising, fear of pain and trait anxiety were explored. Swearing increased pain tolerance, increased heart rate and decreased perceived pain compared with not swearing. However, swearing did not increase pain tolerance in males with a tendency to catastrophise. The observed pain-lessening (hypoalgesic) effect may occur because swearing induces a fight-or-flight response and nullifies the link between fear of pain and pain perception."

If it's really pure, it's the same. You'll need some calcium salt, too. A chloride salt is fine but a bit irritant if too concentrated, the lactate salt is often preferred. Either way, rince well.

Ultrabroadband elastic cloaking in thin plates

Mohamed Farhat, Sebastien Guenneau, and Stefan Enoch

Accepted Monday Jun 15, 2009

Control of waves with metamaterials is of great topical interest, and is fueled by rapid progress in broadband acoustic and electromagnetic cloaks. However, when one moves into the area of elastodynamics, it is no longer possible to design cloaks using conformal mappings.

Anonymous 29/7/2009(Wed)03:43:50 No.145007

We propose a design for a cloak to control bending waves propagating in isotropic heterogeneous thin-plates. This is achieved through homogenization of a multilayered concentric coating filled with piecewise constant isotropic elastic material. Importantly, our cloak displays no phase-shift for both backward and forward scattering. To foster experimental efforts, we finally provide a simplified design of the cloak which is shown to work in more than two octaves frequency range (30 Hz to 150 Hz) when it consits of 10 layers using only 6 differents materials overall. This metamaterial should be easy to manufacture, with potential applications ranging from car industry to anti-earthquake passive systems for smart buildings, depending upon the plate dimensions and wavelengths.

I think those technologies could be boosted by this Carbon Dioxide Air Capture Technology.

Global Research Technologies, LLC (GRT), a technology research and development company, and Klaus Lackner from Columbia University have achieved the successful demonstration of a bold new technology to capture carbon from the air. The "air extraction" prototype has successfully demonstrated that indeed carbon dioxide (CO2) can be captured from the atmosphere. This is GRT�s first step toward a commercially viable air capture device.

This technology debuts at a critical juncture where recent findings of an esteemed array of global experts � including former Vice President Al Gore, Sir Nicholas Stern, and the eminent scientists and practitioners serving on the Intergovernmental Panel on Climate Change � have concluded that man-made climate change is indeed upon us. One of the most critical challenges we face is the dramatically increasing and completely unprecedented level of carbon dioxide in

The carbon capture technology was developed by GRT and Klaus S. Lackner, a professor at Columbia University�s Earth Institute and the School of Engineering and Applied Sciences. The Tucson-based technology company began development of the device in 2004 and has recently successfully demonstrated its efficacy. The air extraction device, in which sorbents capture carbon dioxide molecules from free-flowing air and release those molecules as a pure stream of carbon dioxide for sequestration, has met a wide range of performance standards in the GRT research facility.

"This is an exciting step toward making carbon capture and sequestration a viable technology," said Lackner. "I have long believed science and industry have the technological capability to design systems that will capture greenhouse gases and allow us to transition to energies of the future over the long term."
