(Perhaps Popper is less influential these days, but he was still right about that!) <br /><br />I don't know how important this is to the collaborative process, but I could certainly never work amenably with anyone who believed that Physics conjectures could be "proven". Perhaps you meant to say, "...shown not to be internally inconsistent"?

No powerpoint! ....<br /><br />The Cognitive Style of PowerPoint Prof Edward Tufte Yale Univ His criticism <br />Criticism of PowerPoint[edit]<br />Tufte has criticized the way Microsoft PowerPoint is typically used. In his essay "The Cognitive Style of PowerPoint", Tufte criticizes many aspects of the software:<br /><br />1. Its use to guide and reassure a presenter, rather than to enlighten the audience;<br />2.Its unhelpfully simplistic tables and charts, resulting from the low resolution of early computer displays;<br />3. The outliner's causing ideas to be arranged in an unnecessarily deep hierarchy, itself subverted by the need to restate the hierarchy on each slide;<br />4.Enforcement of the audience's lockstep linear progression through that hierarchy (whereas with handouts, readers could browse and relate items at their leisure);<br />5. Poor typography and chart layout, from presenters who are poor designers or who use poorly designed templates and default settings (in particular, difficulty in using scientific notation);<br />6. Simplistic thinking—from ideas being squashed into bulleted lists; and stories with beginning, middle, and end being turned into a collection of disparate, loosely disguised points—presenting a misleading facade of the objectivity and neutrality that people associate with science, technology, and "bullet points".<br />7. Tufte cites the way PowerPoint was used by NASA engineers in the events leading to the Space Shuttle Columbia disaster as an example of the many problems. The software style is designed to persuade rather than to inform people of technical details. Tufte's analysis of a NASA PowerPoint slide is included in the Columbia Accident Investigation Board’s report—including an engineering detail buried in small type on a crowded slide with six bullet points, that if presented in a regular engineering white paper, might have been noticed and the disaster prevented.[14][15]<br /><br />Instead, Tufte argues that the most effective way of presenting information in a technical setting, such as an academic seminar or a meeting of industry experts, is by distributing a brief written report that can be read by all participants in the first 5 to 10 minutes of the meeting. Tufte believes that this is the most efficient method of transferring knowledge from the presenter to the audience and then the rest of the meeting is devoted to discussion and debate.<br />From <br />https://en.wikipedia.org/wiki/Edward_Tufte<br />Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-5439168179960787195.post-77407486056664095562017-07-16T00:18:09.140+10:002017-07-16T00:18:09.140+10:00Good point.

The other way around one doubts it. The fact that more physicists have won Nobel prizes in chemistry is a testimony to this. Even in engineering many aspects is physics on a large scale. Mass transfer with chemical reaction considered as the intellectual triumph of chemical engineering can be described as the physics of chemical kinetics.

Henry's example is not really an instance of open science in physics, as the open part was purely mathematical: proving the positivity of a particular determinant. <br /><br />It seems that the problems that work best involve both a conjecture and a strategy, perhaps one that is "elementary" (in the mathematical sense of not involving preexisting technical machinery) so that one can most benefit from the wisdom of the crowd. <br /><br />One CAN think of sharp questions in theoretical physics. An example: Is there long range order in the ground state of the 2D spin-1/2 Heisenberg antiferromagnet? Although almost everyone believes this on the basis of approximate treatments and numerics, very few physicists have the inclination or ability to address the proof. I would probably go as far as to say that once a question has been posed sufficiently precisely to be understood unambiguously, it has effectively become mathematics. That's why you can put up a cash prize for a solution of a specific math problem. <br /><br />Would love to hear of counterexamples, of course!Austenhttps://www.blogger.com/profile/05639020827408234405noreply@blogger.comtag:blogger.com,1999:blog-5439168179960787195.post-82053439324946534622017-07-11T10:14:36.155+10:002017-07-11T10:14:36.155+10:00There is a nice example in physics for determinant...There is a nice example in physics for determinant quantum Monte Carlo (DQMC) of open science working really well. Terrance Tao is even involved. I couldn't do a better summary than the original source I read it on, but the entire process was done on mathoverflow, and there is a resulting paper (in PRL). The paper is interesting to read because it tries to give credit to everyone that contributed, but many were anonymous.<br /><br />Here is the original blog post I read about it:<br />https://thiscondensedlife.wordpress.com/2015/05/15/sign-problems-terry-tau-and-open-science/Henry Noursehttps://www.blogger.com/profile/00258020187476688658noreply@blogger.comtag:blogger.com,1999:blog-5439168179960787195.post-44260291051594734402017-07-11T02:19:44.516+10:002017-07-11T02:19:44.516+10:00The problem for that idea in theoretical chemistry...The problem for that idea in theoretical chemistry is that the "big" problems are seen as being in physics (left to physicists) or biology, where big ideas or big computers are seen as what is needed, not big teams.dtvmcdonaldhttps://www.blogger.com/profile/07594633209626059331noreply@blogger.comtag:blogger.com,1999:blog-5439168179960787195.post-92156879373714842972017-07-08T06:06:48.448+10:002017-07-08T06:06:48.448+10:00I would fully endorse it for theoretical physics i...I would fully endorse it for theoretical physics if you were to start such a program --- it needs someone established/prominent and with this mind-set to kick things off.
