Think about your team-what are the types of people on your team?
Have you ever wondered why some teams are so quick to work together and others are not? The ultimate understanding is the chemistry. When the chemistry is right teams work. In the event your team is not jelling follow these six quick tips
1.Share responsibility among all team members. This is one of the easiest ways to get the team to develop mutual accountability. If team members know they must count on each other then each member does not want to be the one to let the team down.
2.Get everyone to know each person's strengths and weakness. This will aid in getting everyone to build on each other. We cannot all share the same strength so when Sharon's strength can assist Bob's weakness, it creates a win-win for the team.
3.Team as well as member role understanding. Too often team members do not understand how what they are doing plays vision of the organization. This is critical on an individual basis as well as having the team know what the entire team does for the benefit of the whole organization.
4.Encourage members to praise each other. Like Canadian Geese that honk along their flight it is important for team members to motivate and encourage each other. One of the largest misconceptions in business today is that motivation must come from management. Motivation must come from within and each member can play a part in increasing others' desires to improve and self motivate.
5.Get everyone to know something on a personal level about each other. This one is a little sticky with some employees because they feel they are there to work and not to socialize. While on the surface this is 100% correct - it has been shown that when employees know something about each other they can more easily empathize and help the team to grow stronger. Key factor here - do not force the issue with someone who absolutely does not want to share. Give them time to come around or if they do not they may naturally see they are not a good fit for this team and may leave of their own accord.
6.Encourage open communication up the chain of command. When employees feel 100% comfortable in coming to the team leader about issues, then the team grows significantly. Be careful not to talk outside of class here. One of the best tools can easily become a deadly one if the leader shares personal information. The critical part here is to make sure the entire team recognizes this and follows suit. Everyone needs to remember, you can do one of three things when you talk with an employee or co-worker.
1.In one ear and out the other
2.In one ear and into your heart and soul
3.In one ear and out the mouth

Nasa Tests Fiber Optic Wing Shape Sensors

The Ikhana unmanned aircraft system has been used by NASA last year to fight wildfires from the sky and this month to provide images of current Californian wildfires to authorities (link to NASA images). But Ikhana is also used to evaluate advanced sensing technology installed on its wings to improve its efficiency. The new sensors, which incorporate fiber optic sensing technology, are located side by side with traditional sensors. As said one NASA researcher, ‘there are 3,000 sensors on Ikhana that are imperceptibly small because they’re located on fibers approximately the diameter of a human hair.’ But read more…The sensors are so small that they’re almost invisible. “Although the new sensors on the Ikhana, which are located on fibers that are the diameter of a human hair, are not visible, the sealant used to apply them can be seen in this view from above the wing.” (Credit: NASA photo by Tony Landis) Here are two links to a larger version of this picture and to a Ikhana photo collection.
How these fiber optics sensors could improve aircraft efficiency? “The weight reduction that fiber optic sensors would make possible could reduce operating costs and improve fuel efficiency. The development also opens up new opportunities and applications that would not be achievable with conventional technology. For example, the new sensors could enable adaptive wing-shape control. ‘Active wing-shape control represents the gleam in the eye of every aerodynamicist,’ [said Lance Richards, Dryden’s Advanced Structures and Measurement group lead.° ‘If the shape of the wing can be changed in flight, then the efficiency and performance of the aircraft can be improved, from takeoff and landing to cruising and maneuvering.’”
And where are located these new sensors? “Six hair-like fibers located on the top surface of Ikhana’s wings provide more than 2,000 strain measurements in real time. With a combined weight of less than two pounds, the fibers are so small that they have no significant effects on aerodynamics. The sensors eventually could be embedded within composite wings in future aircraft. To validate the new sensors’ accuracy, the research team is comparing results obtained with the fiber optic wing shape sensors against those of 16 traditional strain gauges co-located on the wing alongside the new sensors.”
These fiber optic sensor systems could also improve safety. “Another safety-related benefit of the lightweight fiber optic sensors is that thousands of sensors can be left on the aircraft during its lifetime, gathering data on structural health and performance. By knowing the stress levels at thousands of locations on the aircraft, designers can more optimally design structures and reduce weight while maintaining safety, Richards explained. The net result could be a reduction in fuel costs and an increase in range. Further, intelligent flight control software technology now being developed can incorporate structural monitoring data from the fiber optic sensors to compensate for stresses on the airframe, helping prevent situations that might otherwise result in a loss of flight control.”

Physics. Vomit Comet.?
The “Vomit Comet.” In Zero-gravity astronaut training equipment testing, NASA flies a KC135A aircraft along a parabolic flight path. As shown in Figure P4.47, the air-craf climbs from 24000ft to 31000ft, where it enters the zero-g parabola with a velocity of 143m/s nose-high at 45.0 degrees and exits with velocity 143m/s at 45.0° nose-low. During this portion of the flight the aircraft and objects inside its padded cabin are in free fall; they have gone ballistic. The aircraft then pulls out of the dive with an upward acceleration of 0.800g moving in a vertical circle with radius 4.13km (During this portion of the flight occupants of the aircraft perceive an acceleration of 1.8g).
What are the aircraft's
a.) speed
b.) altitude at the top of the maneuver?
c) What is the time interval spent in zero gravity?
d.) What is the speed of the aircraft at the bottom of the flight path?
Diagram can be found here: http://www.fen.bilkent.edu.tr/~mb/phys101/CH4.pdf
nice question
The 45 degree means it's horizontal and vertical speed components are equal in magnitude and that particular moment, and are each V/sqrt(2)=101.11m/s (V=143m/s)
The vertical component goes to zero at the top of the maneuver, so a) 101m/s.
c) in a free fall it's vertical speed component changes as v=v0+g*t, and v=0 at top, so t=v0/g=10.3s
b) starting at 31000ft=9448.8 m (checked with google 
) it goes up by another h=gt^2/2=521 m, so in total 9970 m = 32710ft (why mix the units here?)
d) with a=v^2/r, a=1.8g=1.8*9.8 m/s^2 and r=4130m v=sqrt(ar)=270m/s
Alan B. Shepard Jr. Is Dead at 74; First American to Travel in Space
Alan B. Shepard Jr., the first American to fly in space, lifting national spirits at a decisive moment of cold war anxiety, and later one of only 12 astronauts to walk on the Moon, died late Tuesday night at a hospital in Monterey, Calif. He was 74 and lived in Houston and Pebble Beach, Calif.
