Math Connections Take Students Far
By Brandon Rodriguez

A Los Angeles math teacher gets students engaged with connections to science and exploring the human side of math, such as how leaders inspire change in their communities.

Katherine Risbrough has been teaching high school math for almost 10 years. She began her teaching career in the Hickory Hill community of Memphis, Tennessee, where she taught everything from Algebra 1 to Calculus and served as a math coach for the district. Five years ago, she came to Los Angeles to teach Integrated Math and Calculus at Synergy Quantum Academy High School. 
Outside of math, Ms. Risbrough is also a superfan of college football and never misses a game at her alma mater, the University of Southern California. Her fandom for making the game is rivaled only by her love of Harry Potter, having been to every midnight book and movie release. 
I caught up with Ms. Risbrough to find out how she gets students excited about math, and I learned about a new strategy she used this past year: bridging math and science by teaming up with the AP Physics teacher.

History
U.S. President Dwight Eisenhower displaying the surviving 3rd Re-Entry Test Vehicle program mock warhead during a televised speech on November 7, 1957. Credit: National Air and Space Museum, Smithsonian Institution The technology and hardware developed for this re-entry test series led to America's first successful satellite. After the humiliating launch pad explosion of the Navy's Vanguard project launch attempt in December 1957, JPL and the Army Ballistic Missile Agency were allowed to try. They succeeded spectacularly with Explorer 1 on January 31, 1958. Explorer I went beyond Sputnik by carrying the first space experiment, a Geiger counter developed by James Van Allen, which discovered belts of trapped radiation encircling Earth. Launch of Explorer 1, January 31, 1958. Credit: NASA/JPL-Caltech From JPL to NASAWith Explorer I, JPL vaulted the U.S. into space and prompted the formation of NASA. On December 3, 1958, two months after NASA started operations, JPL was transferred from Army jurisdiction to that of the new civilian space agency. The laboratory brought to NASA experience in building and flying spacecraft, an extensive background in solid and liquid rocket propulsion systems, guidance, control, systems integration, broad testing capability, and expertise in telecommunications using low-power spacecraft transmitters and very sensitive Earth-based antennas and receivers. The Laboratory now covers some 168 acres (68 hectares) adjacent to the site of the early rocket experiments. It is NASA's only Federally Funded Research and Development Center, operated for the agency by Caltech. JPL in 2015. Credit: NASA/JPL-Caltech JPL creates its nicheIn the 1960s, JPL began to develop robotic spacecraft to explore other worlds. This effort began with the Ranger and Surveyor missions to the Moon, paving the way for NASA's Apollo astronaut lunar landings. Rangers 7, 8, and 9, launched in 1964 and 1965, took photos of the Moon as they descended toward intentional impacts. In 1966 through 1968, Surveyors 1, 3, 5, 6 and 7 made soft landings on the Moon. Ranger 6 under construction, September 24, 1963. Credit: NASA/JPL-Caltech During that same period and through the early 1970s, JPL carried out Mariner missions to Mercury, Venus and Mars.

Kurt Thome serves as the Terra Project Scientist at NASA’s Goddard Space Flight Center, making sure that the data Terra collects is of the highest quality and that the information continues to support and build upon existing knowledge. “We still play a key role in understanding the earth’s atmosphere and surface,” he says.
Thome was always fascinated with science and the sky.  As a third grader he wanted to be a weatherman. He liked looking at the sky and going to the Museum of Science and Industry in Chicago. “There are two things that children who like looking at the sky want to become, astronomers or weathermen.  If you’re parents don’t let you out after dark, you really only have one choice,” says Thome.
Thome earned his bachelor’s degree from Texas A and M University in meteorology and his masters and doctorate from the University of Arizona in atmospheric sciences.
Turbofan Thrust
F = (m dot * V)f - (m dot)f * V0 + (m dot * V)e - (m dot)c * V0


We can combine the terms multiplying V0 and use the definition of the
bypass ratio bpr to obtain the final thrust equation:


F = (m dot * V)e + bpr * (m dot)c * Vf - (m dot * V)0



Because the fuel flow rate for the core is changed only a small
amount by the addition of the fan, a turbofan generates more thrust
for nearly the same amount of fuel used by the core. This means that
a turbofan is very fuel efficient. In fact, high bypass ratio
turbofans are nearly as fuel efficient as turboprops.
Because the fan is enclosed by the inlet and is composed of many
blades, it can operate efficiently at higher speeds than a simple
propeller. That is why turbofans are found on
high speed
transports
and propellers are used on
low speed
transports. Low bypass ratio
turbofans are still more fuel efficient than basic turbojets. Many
modern fighter planes actually use low bypass ratio turbofans
equipped with afterburners. They can then
cruise efficiently but still have high thrust when dogfighting. Even
though the fighter plane can fly much
faster
than the speed of sound,
the air going into the engine must travel less than the speed of
sound for high efficiency. Therefore, the airplane inlet slows the
air down from supersonic speeds.

You can explore the design and operation of an afterburning turbojet
engine by using the interactive
EngineSim
Java applet. Set the Engine
Type to "Turbofan" and you can vary any of the parameters which
affect thrust and fuel flow.

Planetary Exploration Test Facilities

There are several state-of-the-art test rigs and facilities at the NASA Glenn Research Center (GRC) operated by GRC’s mTRAX Planetary Exploration team.  These rigs serve to test planetary roving vehicle systems and components in simulated planetary and lunar conditions.
Facility Overview

There are several state-of-the-art test rigs and facilities at the NASA Glenn Research Center (GRC) operated by GRC’s mTRAX Planetary Exploration team.  Most of the facilities are located in the Engine Research Building (ERB). These rigs serve to test planetary roving vehicle systems and components in simulated planetary and lunar conditions.    Most of the test capabilities are focused on the interactions between rover components (such as tires and excavation tools) and the terrain, though there are environmental test capabilities as well.  A few examples of ongoing research in these labs includes conducting full-scale vehicle mobility tests to determine new methods for traversing challenging terrain, evaluating the performance of novel rover tires in lunar and Martian environments, and testing various excavation techniques for digging on the Moon.
Capabilities
The following test rigs and facilities all fall under the mTRAX Planetary Exploration umbrella:
Simulated Lunar OPErations (SLOPE) Lab
The Simulated Lunar OPErations (or SLOPE) Lab serves to provide controlled test conditions to evaluate the tractive performance of roving vehicles on simulated Lunar and Martian terrain.  Because the lab is indoors, the facility has stable temperature and humidity levels which limits variability in soil conditions between tests.  Full-scale vehicles, or sub-systems and components, can be tested here.

Gateway Deep Space Logistics
As astronauts conduct missions at Gateway and prepare for lunar surface missions, they will need deliveries of critical pressurized and unpressurized cargo, science experiments, and supplies like sample collection materials. In March 2020, NASA announced SpaceX as the first U.S. commercial provider under the Gateway Logistics Services contract to deliver cargo and other supplies to Gateway.

'Start Early and Start Now' — Insights From CalPERS Benefits Education Events - CalPERS PERSpective
Chien “Cathy” Chien (center), 32, California Department of Health Care Services
“Start early, and start now,” is Cathy Chien’s motto when it comes to saving extra to supplement her eventual CalPERS pension. At 32, the California Department of Health Care Services worker has two CBEEs under her belt, and she’s not done learning.
“Every time I come here, I get new information,” said Chien. “I began a 457 plan after my first CBEE — it’s important to know your income options beyond what’s already in place.”
Chien said the deferred compensation plans available through CalPERS can be better than what’s available through other avenues. “I’m planning for my future today, because you never know what can happen,” she said. “You can’t put a price on the feeling of knowing you’ll have enough money in retirement, because you took the time to educate yourself early in your career.
“Knowing I will be ok when I retire is priceless.”

Our next CBEE will be held virtually April 10 and 11, and registration opens in early March. Subscribe to our Member Education Bulletin to be notified of future educational events in your region.
