Seminar: You and Your Research, Dr. Richard W. Hamming (March 7, 1986) - 10 views

  • This talk centered on Hamming's observations and research on the question "Why do so few scientists make significant contributions and so many are forgotten in the long run?" From his more than forty years of experience, thirty of which were at Bell Laboratories, he has made a number of direct observations, asked very pointed questions of scientists about what, how, and why they did things, studied the lives of great scientists and great contributions, and has done introspection and studied theories of creativity. The talk is about what he has learned in terms of the properties of the individual scientists, their abilities, traits, working habits, attitudes, and philosophy.

    Here's the link related to one of the lunch time discussions. I recommend it to every single one of you. I promise it will be worth your time. If you're lazy, you have a summary here (good stuff also in the references, have a look at them):      Erren TC, Cullen P, Erren M, Bourne PE (2007) Ten Simple Rules for Doing Your Best Research, According to Hamming. PLoS Comput Biol 3(10): e213.

    I'm also pretty sure that the ones who are remembered are not the ones who tried to be... so why all these rules !? I think it's bullshit...
  •  
    The seminar is not a manual on how to achieve fame, but rather an analysis on how others were able to perform very significant work. The two things are in some cases related, but the seminar's focus is on the second.
  •  
    Then read a good book on the life of Copernic, it's the anti-manual of Hamming... he breaks all the rules !
  •  
    honestly I think that some of these rules actually make sense indeed ... but I am always curious to get a good book recommendation (which book of Copernic would you recommend?) btw Pacome: we are in Paris ... in case you have some time ...
  •  
    I warmly recommend this book, a bit old but fascinating: The sleepwalkers from Arthur Koestler. It shows that progress in science is not straight and do not obey any rule... It is not as rational as most of people seem to believe today. http://www.amazon.com/Sleepwalkers-History-Changing-Universe-Compass/dp/0140192468/ref=sr_1_1?ie=UTF8&qid=1294835558&sr=8-1 Otherwise yes I have some time ! my phone number: 0699428926 We live around Denfert-Rochereau and Montparnasse. We could go for a beer this evening ?

Vertical Farming is Already Here- Organitech - 2 views

    Great!! The typical Dutch tomato differs from the typical Dutch cucumber only by its color, not by its taste, we all know this. In vertical farming I guess the next step to the UGV (uniform garbage vegetable) will be made. Perhaps now they only differ by its geometrical form, the color is the same for all vegetables, who knows??
  •  
    right ....... ok .......... so whats your point?
  •  
    Point?? As a professional bullshitter I don't have a point. Just grouch, never critizise (freely translated from the Austrian principle "Nur raunzen, nie kritisieren!") :-) If I have sort of a point: I'd rather not try the vegetable they produce in this "vertical farming", Dutch experience was by far enough.

Let's Reconstitute Humans From Genomes Launched Into Space! and Other Ambitious Proposa... - 0 views

  • Fragmented human genomes could be shipped toward the stars and reconstructed upon their arrival,
  • to spur the monumental technology advances that would be required for such a feat. So the 100-Year Starship is more like a thought experiment than a construction project.

    anything happening on this since 3 years?

    yes it seems like. most of it seems however directed toward understanding this effect, and not toward applications.

Experiments Confirm the Influence of Genome Long-Range Correlations on Nucleosome Posit... - 0 views

  •  
    From the statistical analysis of nucleosome positioning data for chromosome III of S. cerevisiae, we demonstrate that long-range correlations (LRC) in the genomic sequence strongly influence the organization of nucleosomes.

BBC NEWS | Asia-Pacific | Scientists bring snow to Beijing - 2 views

  •  
    Did you know about this Weather Modification Office? Promising or dodgy?
  •  
    Yes. In China it happens apparently quite often that weather is regionally modified, e.g. in order to have good weather conditions during certain events (like olympics in Beijing). But also in other countries weather modification is applied, for reasons of agriculture, pollution, skiing, etc. Obviously, one wonders on the environmental impact of such an artificial cloud feeding process with silver iodide. I just googled, stumbling upon this report http://www.weathermodification.org/AGI_toxicity.pdf which published the result: no environmentally harmful effects...
  •  
    and w.r.t. ur question: I mean different weather conditions which we experience locally (like droughts or other extreme weather events) are (often) due to large-scale/global climatic changes. Hence, cloud seeding just describes a local, short-term mitigation of these events. However, there is a geoengineering proposal (so climate modification) which also suggests to seed clouds above the sea (i.e. increase cloud coverage, e.g. by using seaspray as cloud condesation nuclei), thereby increasing the planetary albedo (Earth reflectance) and reducing the energy reaching the Earth surface. If this idea is promising or not, I couldn't judge upon, but for sure it is worthwhile to take a closer look at.

The Art of Community - 3 views

  •  
    A recently-published book by the Ubuntu Community Manager, Jono Bacon. I just started reading it: lots of information, experiences and revealing hints on how open-source communities are born and evolve today.
  •  
    "Since I released The Art of Community, one thing has become evident: the people who are buying it are awesome. If you have bought it you are awesome. If you have not, you too can be awesome." To me seems more interesting the topic than the author. I have the impression that many people in this community behave like high-school pupils, though their production it's absolutely "awesome".

Physics - Fruit flies swim through air - 1 views

  • A new experiment reported in Physical Review Letters shows that—contrary to popular wisdom—paddling can be as effective in air as it is in water. This could imply that insects evolved their flight capability from some earlier swimming trait.
  • Using high-speed video cameras to track wing motion, the team observed certain cases where the flies paddled their wings forward and backward. To confirm that this was indeed drag-based motion, the team plugged their wing data into an “insect flight simulator” and found that they could reproduce the fly’s overall movement. The authors constructed a simple model of paddling, which seems to support the theory that insect wings evolved in water.

    I was into this some time ago and found a documentary in which they performed an experiment on a guy. Long story short, it didn't work that good. He was semi-lucid all the time and his mental performance dropped. Perhaps it is possible to survive like this for months, but if your goal is to maximize your daily output, you will not gain extra work hours due to being 3/4 conscious most of the time. EDIT: Not related to the documentary I mentioned but some first hand stories: http://www.reddit.com/r/IAmA/comments/co5t9/i_attempted_polyphasic_sleep_for_a_documentary_ama/c0tza1e
  •  
    I also heard about it. At the moment, I am on some sort of bi-phasic sleep and I am not feeling more tired than with the monophasic one (while sleeping effectively less right now).
  •  
    If it exists, there's an xkcd about it: http://xkcd.com/320/ Actually the schedule proposed there is quite useful if you're into this whole Friday / Saturday night thing..
  •  
    I don't see why it wouldn't work if you manage to detach yourself from the cycardian input. As in never ever see sun and daylight :))
  •  
    > As in never ever see sun and daylight :)) Like in the Netherlands you mean?

    Tri-phasic sleep rhythm works fine.
