A movie showing a snapshot from a Molecular Dynamics simulation of ethanol (the usual drinking alcohol; methanol, on the other hand is poisonous) interacting with (POPC) lipids. This movie showing how ethanol (blue and red) has hydrogen bonded with (POPC) lipids.
Details: the simulation is in explicit (SPC) water (removed from visualization for clarity). 90 ethanol molecules. Lipids (128 in total): POPC. Gromacs simulation engine.

Hair Simulation : Letter A
Playing with hair simulations, these a little more abstract than the others.
Shown is a 3D, whole-star simulation of the GCD model of a Type la supernova at the moment at which a detonation wave begins to weep through the White Dwarf Star, incinerating it.
At Argonne National Laboratory, Type Ia supernovas, among the brightest exploding stars in the universe, are "cosmic yardsticks" whose application led to the discovery of dark energy. Astrophysicists are creating leadership computing simulations to better understand these explosions and by doing so help observers use them to determine the properties of dark matter.
On 22 May 2015, Singapore Management University (Singapore) won the final round of the International Criminal Court (ICC) Trial Competition, English version, held in ICC Courtroom I in The Hague (Netherlands). Leiden University (The Netherlands) and National Law University, Jodhpur (India) won, respectively, second and third place. The winning team comprised of Annabelle Teo, Samuel Yap, Edmund Koh, Alexis Ang, Shi Hao Foo and Chin Kiat Ong. The Best Speaker award for the English-language competition went to Anabelle Teo of Singapore Management University.
This year, 55 teams comprising a total of 330 participants from 38 countries worldwide participated in the English-language simulation exercise on the applicable law and jurisprudence of the ICC. Before a bench composed of ICC Judge Howard Morrison and ICC Legal Officers Philipp Ambach and Savina Savidis, the teams competed on a fictitious case, presenting oral arguments during an appeals hearing in the roles of Prosecution, Defence and Legal Representatives of a Government.
After a break for deliberations, Judge Howard Morrison announced the bench’s decision and an awards ceremony was held for all participants. The finalists’ peers attended the event in the Court’s public galleries and the event was web streamed live on the Court’s official website.
The ICC Trial Competition is organised by the Grotius Centre for International Legal Studies of Leiden University, The Hague Campus, with the institutional support of the ICC. Also cooperating on the project are the Planethood Foundation, the Ministry of Foreign Affairs of Estonia, the Government of Luxembourg, the Municipality of The Hague, the Ministry of Security and Justice of the Netherlands, Doughty Street International, the European Society of International Law and the Lutfia Rabbani Foundation.
In the context of its Academic Programme, the ICC supports the organisation of ICC Trial Competitions in Chinese, English, Russian, and Spanish, with a view to also support Arabic and French versions in the future. These initiatives play a critical role in galvanising interest in the Court’s work with academic communities as well as in enhancing promotion and respect for international criminal law.

Georgetown University School of Foreign Service in Qatar held a conflict resolution and negotiation simulation titled “Afghanistan in 2015: Chaos in Kabul.” The simulation, organized in conjunction with Georgetown’s Institute for the Study of Diplomacy (ISD) in Washington, D.C., included 25 student participants from the Georgetown Qatar and D.C. campuses, the Academic Bridge Program, as well as local high school students. Canadian Head of Mission to Qatar, Gary Luton, played the role of UN Secretary General in the exercise.
“It’s always useful for practitioners to engage with students on important issues, and to hear their opinions on and reactions to some of the international community’s most vital concerns,” said Luton.
The exercise, a blend of real-world events and fictional elements that help facilitate learning objectives, was designed to help students think about and experience domestic and international efforts towards reconstruction and development after international military forces have pulled out of a country, the power struggle within Afghanistan in particular, and how the UN, foreign governments, the Afghan government, tribal leaders and the Taliban can interact constructively.
Students received a set of “confidential” instructions outlining each team’s initial position on developing a road map for Afghan reconstruction and development several days before the simulation began. During the simulation, students engaged in a series of bilateral and multilateral meetings which culminated in a final session presided by the UN Secretary General, played by the Canadian Head of Mission to Qatar, Gary Luton.
“The value of simulations for students studying international affairs, is that they get to immerse themselves in very difficult topics and learn about the subject matter. They then get to play the role of the people in the real world who are trying to do something about that crisis,” said Jim Seevers, the ISD’s Director of Studies and Training who created the exercise in conjunction with ISD Associate Lt. Colonel Mike Shortsleeve. “The students love the process of actually being the negotiator. When you’re being asked, not just to understand a subject, but to negotiate with a party that you know has a different view, you begin to see issues from different parties’ perspectives,” added Seevers.
During the exercise, students formed several teams representing the Islamic Republic of Afghanistan, the Taliban, the Islamic Republic of Iran, the Islamic Republic of Pakistan, the United States, the People’s Republic of China, and the U.N. Assistance Mission in Afghanistan. A “control room” of faculty and policy practitioners played the role of the Afghan Tribal Leaders and ISAF/NATO.
Ysa Chandna, a Georgetown University student, commented, “Crisis Simulation is perhaps the best thing at Georgetown University; this is my third time taking part in it and I’m very glad I did because I learned a lot from it.”.

The ‘Poverty Trap’ simulation took the entire year group into a school-based simulation of a slum in a developing country.
View from the cockpit of the simulator. Multiple screens provide a view similar to what one would see in a snowplow on the road.
This is how I see Machine To Keep A Feather In The Air working (if it works at all). The simulation is not that accurate of course, and there is a lot more code that needs to go into it still, the outer fans should do more to keep the balloon in the middle for instance.
The idea is that the "balloon" here will later be replaced by a vision system that tracks the object in real life and passes the information along to the simulation, some of the same rules should apply with tuning that system, such as for instance "don't blow on the object if it is moving upwards" and "ignore the object unless it is below a certain height".
Also, I'll be wanting to use as few (pan/tilt servo pairs + fan) as possible, 5 seems like a good number.
