Road-tested photo gear : Travel Tips. From road-tested tripods to essential photo-related apps, we asked a few well-travelled professional shutterbugs to weigh in on the best gear for snapping photos. While most of their advice is aimed at travellers that own digital single-lens reflex cameras (DSLRs), their strategies for capturing great images can be of interest to any photographer. A tripod that’s adaptable and travel-friendly Specialising in architecture and interior photography, Dubai-based photographer Catalin Marin has travelled the world and runs a personal blog, A Momentary Awe.

Besides a camera, Marin’s most essential travel gear is a sturdy, lightweight tripod. His choice at the moment is the Gitzo GT3541, which folds down to only 55cm and extends to 132cm without the head. A good lens to snap the clearest of travel images Reena Bammi, a professional travel-and-lifestyle magazine photographer, said that “a good lens is more important than a fancy camera.” Sean O'Neill is the tech travel columnist for BBC Travel. Online Education Startup Coursera Lands $16M From Kleiner & NEA, Adds John Doerr To Its Board.

It has already been a year since Peter Thiel called public attention to the bubble growing in American higher education. Yet, the cost of receiving a college degree in the U.S. has continued to grow, as student debt in the U.S. today has pushed north of $1 trillion, with the average debt per student standing at more than $25,000. With the current fiscal trajectory of our educational system now unsustainable, an infusion of new blood has begun to enter the space, and a growing number of startups and entrepreneurs have turned their focus to upgrading education’s legacy infrastructure. In turn, investors now seem ready to provide edtech companies with the type of capital that has typically been reserved for consumer businesses. The latest example of this trend is the Mountain View-based Coursera, one of a growing set of edtech startups looking to combat the rising costs now endemic to higher education with smart, scalable, web-based solutions.

DNA/How to Stop Worrying and Learn to Love the Internet. This piece first appeared in the News Review section of The Sunday Times on August 29th 1999. A couple of years or so ago I was a guest on Start The Week, and I was authoritatively informed by a very distinguished journalist that the whole Internet thing was just a silly fad like ham radio in the fifties, and that if I thought any different I was really a bit naïve. It is a very British trait – natural, perhaps, for a country which has lost an empire and found Mr Blobby – to be so suspicious of change. But the change is real. I don’t think anybody would argue now that the Internet isn’t becoming a major factor in our lives.

However, it’s very new to us. Then there’s the peculiar way in which certain BBC presenters and journalists (yes, Humphrys Snr., I’m looking at you) pronounce internet addresses. 1) everything that’s already in the world when you’re born is just normal; Apply this list to movies, rock music, word processors and mobile phones to work out how old you are. Interactivity. Memory in the Brain [Interactive] Although most people think of memory as a vault for storing information, it is more like a seamstress who stitches together logical threads into scenes that make sense.

In this view, a good memory is therefore not one that holds lots of data but that can deftly separate what is useful from what could distract or upset you. Getting rid of what is not necessary—forgetting—is thus an important part of memory and of thought. It is also critical to emotional wellbeing. Revisiting bad memories is hardly a formula for happiness, after all. To learn more about memory and the power of forgetting, see the January 2012 Scientific American Mind.

The Physics of Leap Day : Starts With A Bang. “When in doubt, make a fool of yourself.

There is a microscopically thin line between being brilliantly creative and acting like the most gigantic idiot on earth. So what the hell, leap.” -Cynthia Heimel Once every four years, the elusive entity that is today — February 29th — comes along. The historical origins and urban legends associated with it are incredibly interesting, but the reason there’s any such thing as Leap Day at all is because of the physics of planet Earth. Image credit: Mrs. Snyder at the Seven Hills School. The Earth, of course, is rotating on its axis while simultaneously revolving around the Sun. And you probably learned that a day is 24 hours, due to the rotation, while a year is 365 days (with an occasional 366 for leap years), taking care of the revolution.

Image credit: Larry McNish at RASC Calgary Centre. The Earth completes a full rotation in less than 24 hours: 23 hours, 56 minutes and 4.09 seconds, to be more precise. What am I talking about? Dauger Research, Inc. - Real-Time Visualization of Quantum Atomic Orbitals. Unlike other tools in this category, this program raytraces through a three-dimensional cloud density that represents the wavefunction's probability density and presents its results in real-time (up to 48 frames per second on Mac G3s; even faster on the latest hardware).

The user interface is very interactive and provides a wide degree of flexibility. It contains all 140 eigenstates up to the n=7 energy level and the allowed spectral transitions between those eigenstates. The Mac version also allows a state formed by a superposition (see below) of up to eight of those eigenstates allowing for over 3 trillion possible states and can display a wavefunction as a picture of a cloud, use color as phase, plot in red-cyan left/right for 3D glasses, and slice the wavefunction. You can see more example images at the bottom of the page. What is Quantum Mechanics? One of the great advances in human knowledge of the twentieth century is the birth of the theory of Quantum mechanics. What are Orbitals? Essential Biochemistry. Mechanism of Translation of mRNA by tRNA in Ribosomes | Animations | PharmaXChange.info.

Protein biosynthesis requires that genes which are coded onto DNA be decoded to the sequence of amino acids which are to be assembled. The DNA is located in the nucleus of the cell, while the amino acids required for the synthesis are located in the cytosol. The encoded sequence for a protein is transcribed onto a messenger RNA (mRNA) which carries the information in the form of a sequence to the cytosol. Here the transcribed “message” from the DNA is translated by the ribosome to produce the protein.

Hence protein biosynthesis involves two crucial steps of TranscriptionTranslation Translation of mRNA is done by the ribosomes which decodes the mRNA sequence and fits the appropriate transfer RNA (tRNA) which contains the appropriate amino acid attached to it. The above animations has been supplied by Dr. Slide 2: A 50S ribosomal subunit then joins the initiation complex to form a 70S ribosome. Slide 3: There are three sites on the ribosome. David L. Home.

The structure of the ion looks like this: In this case, the "ear pieces" are the nitrogen atoms of the NH2 groups - and the "bit that goes over your head " is the -CH2CH2- group. If you were going to draw this in an exam, you would obviously want to draw it properly - but for learning purposes, drawing all the atoms makes the diagram look unduly complicated! Notice that the arrangement of the bonds around the central metal ion is exactly the same as it was with the ions with 6 water molecules attached. The only difference is that this time each ligand uses up two of the positions - at right angles to each other. Because the nickel is forming 6 co-ordinate bonds, the co-ordination number of this ion is 6, despite the fact that it is only joined to 3 ligands.

Co-ordination number counts the number of bonds, not the number of ligands. Cr (C2O4)3 3- This is the complex ion formed by attaching 3 ethanedioate (oxalate) ions to a chromium(III) ion. A quadridentate ligand A hexadentate ligand.

Radioactivity and Electricity Teaching Resources | Furry Elephant. Amit Patel’s Home Page. I’m helping people make games, at Red Blob Games, by investigating and explaining game algorithms, especially maps (grids, paths, procedural generation) and simulations (transportation, economics, complex systems, AI). I’m also building interactive explanations. I find that I learn best when combining the language side of my brain (reading, formulas) with the visual side of my brain (illustrations, interaction). I want to learn not only by reading something or watching something, but by playing with it. Right now I’m mostly focused on small, self-contained articles, but I’m also interested in interactive textbooks. I try to spend one day a week meeting with people working on games, education, big data, or visualization.

Brownian Motion - The Research Goes On ... 8.3 Laser evaporation of Copper Aerosol 9. Conclusion 10. References 11. Appendices "Brownian motion, isn't that the Physics theory I studied in high school? " This is the very instinctive reaction for most of us when encountering the term "Brownian motion". 1. Human lives are full of uncertainties, as with many natural phenomena. 2. Brownian motion is a sophisticated random number generator, based on a process in plants discovered by Robert Brown in 1827(Figure 1). It was only in 1905 when a quantitative analysis was brought about, where Einstein[1] succeeded in stating the mathematical laws governing the movements of particles on the basis of the principles of the kinetic-molecular theory of heat.

Fig. 1. 3. The 'Elementary theory of Brownian motion' is one of the major investigations by Einstein on the Brownian movement theory in 1908. In an undissociated dilute solution, there is a process of diffusion(*), which is caused by the Brownian motion of the suspended thermal molecules. 4. Humanistic Texts. Rogerebert.com :: Movie reviews, essays and the Movie Answer Man from film critic Roger Ebert. The best films of the decade. "Synecdoche, New York" is the best film of the decade. It intends no less than to evoke the strategies we use to live our lives. After beginning my first viewing in confusion, I began to glimpse its purpose and by the end was eager to see it again, then once again, and I am not finished.

Charlie Kaufman understands how I live my life, and I suppose his own, and I suspect most of us. Faced with the bewildering demands of time, space, emotion, morality, lust, greed, hope, dreams, dreads and faiths, we build compartments in our minds. It is a way of seeming sane. The mind is a concern in all his screenplays, but in "Synecdoche" (2008), his first film as a director, he makes it his subject, and what huge ambition that demonstrates. Very few people live their lives on one stage, in one persona, wearing one costume. But already "Synecdoche" has me thinking in terms of the film's insight. In the earlier scenes, he was married to Adele (Catherine Keener). 2. 3. 4. 5. 6. 7. 8. 9. 10. The Digital Humanities and the Transcending of Mortality.

This is a blog. There, I’ve said it. I have been resisting saying it — I have always referred to this space as a “column” — not only because “blog” is an ugly word (as are clog, smog and slog), but because blogs are provisional, ephemeral, interactive, communal, available to challenge, interruption and interpolation, and not meant to last; whereas in a professional life now going into its 50th year I have been building arguments that are intended to be decisive, comprehensive, monumental, definitive and, most important, all mine. In “Changing Places” and “Small World,” the novelist David Lodge fashions a comical/satirical portrait of a literary critic named Morris Zapp, whose ambition, as his last name suggests, is to write about a topic with such force and completeness that no other critic will be able to say a word about it.

The job will have been done forever. The obstacle to this happy state is mortality itself. God vs. Science. There are two great debates under the broad heading of Science vs. God. The more familiar over the past few years is the narrower of the two: Can Darwinian evolution withstand the criticisms of Christians who believe that it contradicts the creation account in the Book of Genesis? In recent years, creationism took on new currency as the spiritual progenitor of "intelligent design" (I.D.), a scientifically worded attempt to show that blanks in the evolutionary narrative are more meaningful than its very convincing totality.

I.D. lost some of its journalistic heat last December when a federal judge dismissed it as pseudoscience unsuitable for teaching in Pennsylvania schools. But in fact creationism and I.D. are intimately related to a larger unresolved question, in which the aggressor's role is reversed: Can religion stand up to the progress of science? The Greatest Advice Book of All Time: Letters From A Stoic by Seneca. "Make your own Bible. Select and collect all the words and sentences that in all your reading have been to you like a blast of triumph Shakespeare, Seneca, Moses, John and Paul. " -- Emerson Today we complete the books of our Advice Bible, adding the last of The Five Greatest Advice Books of All Time. Here is the completed countdown: (5) the Japanese book of Samurai wisdom, Bushido (4) How to Win Friends and Influence People by Dale Carnegie, (3) The Letters of Emerson (2) Climbing the Blue Mountain by Eknath Easwaran, and now, our Number One, Letters From A Stoic by Seneca, translated by Robin Campbell.

For those of you who are wondering about books left off, I excluded religious books, biographies and fiction. What does a long-dead stoic have to say to us? The last one stuck, and he was condemned to death via suicide. Seneca's stoicism draws its strength from bringing oneself into conformity with Fate and divine will. Modern life leaves us stretched between "what else? "
