NASA! NASA! NASA!

Standard

On June 27th 2013, IRIS satellite was successfully launched at 7:27 pm Pacific Time after deploying from the Vandenburg Air Force Base in California within the Pegasus rocket aboard the Stargazer plane.  As a part of the MSGC (Montana Space Grant Consortium), we all proudly watched the launch from the newly rebuilt planetarium at Bozeman, Montana’s very own Museum of the Rockies. The Pegasus rocket was dropped over the Pacific Ocean at coordinates 36.0 north, 123.0 west. At deployment, the IRIS satellite was dropped for 5 seconds within the the Pegasus rocket from the Stargazer plane at an altitude of 11.89 kilometers (39,000 ft) and flying at a velocity of 243 meters per second (797 ft/sec).  The 3 stage booster rocket than began its sequence to reach its target orbit in the earth’s LEO (Lower Earth Orbit). The target orbit for spacecraft separation was a perigee of 620 kilometers and an apogee of 670 kilometers (385 by 416 miles), giving a semi-major axis of 7,023 kilometers (4,364 miles), 97.89 degrees inclination and a mean local time of the ascending node of 06:02:30.

The MSU (Montana State University) personal involved in this mission includes: 
Charles Kankelborg, Larry Springer, Christina Dunn, Janet Glenn, Stefan Eccles (undergrad), Joseph Shaw (EE), Nathan Pust (EE), Angela DesJardins (MSGC), Randy Larimer (MSGC)

Designed for a two-year mission, IRIS carries an ultraviolet spectrometer attached to a telescope with a diameter of 20 centimeters (8 inches).  IRIS fills a crucial gap in our ability to advance Sun-Earth connection studies by tracing the flow of energy and plasma through this foundation of the corona and heliosphere. The satellite will return images and spectra produced every few seconds, allowing material to be tracked as it passes through the chromosphere. IRIS is the eleventh mission to launch as part of NASA’s Small Explorer (SMEX) program, which is part of the wider Explorer program. The launch of IRIS was the forty-second flight of the Pegasus rocket, and the thirty-second of the Pegasus-XL.  The HXLV was an air-launched rocket, using the first stage of the Pegasus dropped from the Stargazer aircraft that carries the registration number N140SC, to boost a hypersonic flight experiment as part of NASA’s Hyper-X program. The aircraft is named Stargazer after the USS Stargazer from Star Trek, a ship formerly commanded by Captain Picard. Pegasus rocket made its maiden flight on 5 April 1990, carrying the Pegsat and SECS satellites for NASA and the US Navy respectively. Early launches were made using NASA’s NB-52B, nicknamed Balls 8, mostly flying from Edwards Air Force Base.

IRIS will be operated in this orbit, as does not carry any maneuvering thrusters or propellant to change its orbit. You can follow IRIS on their Facebook page :)

¡Celebra Einstein en español con Alaina y Pamela!

Standard

What is your strongest memory of learning something amazing? How about something that you passed on to future generations??? Einstein somehow did it and is being remembered this week at the Emerson Cultural Center here in Bozeman, MT from April 2 to 6.   Come to the Thursday conversation hour April 4th at the Emerson North Grill and we will dedicate part of the hour to touring the Einstein exhibit in Spanish, por supuesto :) At the Emerson North Grill, from 3-4 p.m. for $5.  Enjoy a coffee break and Einstein in Spanish!

“Celebrating Einstein” will be held two years before the centennial anniversary of the discovery of Einstein’s General Relativity. One reason is to raise public awareness of the theory’s significance, the last Einstein prediction that has not yet been observed, Yunes said. The other reason is to prepare materials that will be adapted for future Einstein celebrations elsewhere during the centennial celebration of General Relativity in 2015.

 

Joey Key, education specialist at the Montana Space Grant Consortium and member of the planning committee for “Celebrating Einstein,” added, “It’s also the excitement of where we are in this stage of discovery. This is going to be the next big thing in astronomy, the discovery of gravitational waves. Gravitational waves will tell us something totally new about our universe. It’s going to answer lots of questions.”

¡Qué divertido!

Fibonacci Spiral revised :)

Standard

So, as it turns out, it is a very good thing to have multiple perspectives and to have a solar physicist as one of the tutors on this website. Jason, the math and physics tutor, took one look at the Fibonacci blog post and immediately pointed out a fallacy.    He says, “That is not a Fiboncacci Spiral.”.  I say, “It’s not?!”.  He says, “No.  A Fibonacci spiral has to extend to all the squares sides to represent the cubic recurrence relations of the sequence.”

And he has a very good point.
The picture that I posted:does not well represent the Fibonacci sequence.  On a relative scale, it shows what the sequence should be doing, but it does not allow for the full “Golden Ratio” to show through as in the following representation:

 

Referring to the previous post, we see that the beginning numbers to the Fibonacci sequence are: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, 377, 610, 987, 1597, 2584, 4181, 6765, 10946, 17711, 28657, 46368, 75025, 121393, 196418, 317811, …

It’s important to see how accurate the representation of the sequence can be since the numbers are simply found by adding the 2 numbers previous to it.  It is also very interesting to realize that before the Golden Ratio is neared, it oscillates above and below the Golden Ratio before reaching 1.618.  Although it continues to oscillate on a smaller and smaller ratio.

The number then becomes fixed after the 13th number in the Fibonacci sequence will always equal 1.618, what mathematicians refer to as the Golden Ratio, or the perfect number.

It’s also interesting to notice that the initial starting number CAN be changed and the pattern still oscillates to a value that can follow a proportional Golden Ratio spiral and converge to form a proportionally different sequence.  A really great numerical representation on an Excel spreadsheet can be found here, thanks to the homework of Krista Floer.  Thanks Krista!

Mathematician Mark Barr proposed using the first letter in the name of Greek sculptor Phidias, phi, to symbolize the golden ratio. Usually, the lowercase form (φ) is used. Sometimes, the uppercase form (Φ) is used for the reciprocal of the golden ratio, 1/φ.  Mark Barr was an American mathematician who, in about 1909, gave the golden ratio the name of phi, the first Greek letter in the name of Phidias, the Greek sculptor who lived around 450 BC. Source: http://en.wikipedia.org/wiki/Golden_ratio

So, just to prove that the details matter, our history has shown many artists and architects who have even utilized the Golden spiral in their works.  Leonardo DaVinci, for example, was said to have utilized the building blocks of the Fibonacci sequence when painting his masterpiece ‘The Mona Lisa.’ Here are some representations that I have found:

Bone structure in the human body and face that mimic the Fibonacci sequence are said to appeal more aesthetically to the human eye. Even the reproduction and population of bee colonies appear to follow the Fibonacci sequence.  Since it has been proven to carry such unconscious and natural attraction, I think it is worth the time to spread accurate representation of the Fibonacci sequence.  Read more about this fascinating topic at,  The Fibonacci Sequence : Blueprint of Intelligent Design? written by Dana Newkirk.

Enjoy! Alaina

 Here on the blog, I (Alaina) will post enlightening bits of information. To start it off, I want to share the best (and it’s free) way to practice your Spanish.

GO TO OUR PUBLIC LIBRARY!!!  It is so wonderful. Go straight to the children’s department, ask for Sandra, and she will take you straight to the children’s books in Spanish.   She is also a children’s author of some fabulous books and her enthusiasm will show you the way.

Cuando un libro es demasiado bueno para disfrutarlo en soledad, hay que compartirlo con un amigo.
