New Proof of Pythagorean Theorem Discovered by Two High School Girls in Louisiana
2025-02-22 10:00 - 11:00 | Auditorium
DEDICATED TO BLACK HISTORY MONTH
A New Proof of Pythagorean Theorem Discovered by Calcea Johnson and Ne’Kiya Jackson – two high school girls in Louisiana
by Tagline of Mathematics Club of Science Circle
In 2022, two high school students in New Orleans, Louisiana, discovered a new proof of the well-known, Pythagorean Theorem that equates the square of the hypotenuse c of any RIGHT TRIANGLE ◺abc to the sum of the square of each shorter sides, a, b
Historically, most mathematicians have argued that any attempt to prove Pythagorean Theorem based on trigonometry would necessarily employ circular reasoning because trigonometry is a calculus for the RIGHT TRIANGLE based on Pythagorean Theorem. However, Ms. Johnson and Ms. Jackson used the LAW OF SINES which is easily proven independently of Pythagorean Theorem or its consequences.
Were Pythagoras of Samos (circa 570 BCE – 495 BCE) reincarnated and alive today, and either Ms. Jackson or Ms. Johnson told him of her proof, he would probably insist:
“DON’T TELL ANYONE ABOUT THIS!”
The Pythagorean School was rather CULT-LIKE and secretive, considering their beliefs in reincarnation and mathematical discoveries to be sacred, esoteric knowledge. However, in this presentation, I will take you for a friendly walk through the steps of the proof, while avoiding tedium as much as possible.
So I will share with you how the girls did this remarkable proof!
The proof is of aesthetically beautiful conception and aside from high level language skills, their work cleverly draws on knowledge of all basic High School mathematics: geometry, algebra, TRIGONOMETRY and geometric series – it seems an achievement of WHOLE BRAIN thinking or at least “both left- and right- brain thinking”. We will also discuss the perishable resource of talented, inventive young minds and the vital importance of quality education, fair opportunity and encouragement for ALL young people.

Debate: Online Anonymity
2025-02-08 10:00 - 11:00 | Science Circle Forum
Tired of heated arguments around the dinner table? Getting bored of the blowhards on TV and social media? Wondering why everyone is yelling and/or crying about the state of everything? Then this is the event for you.
A debate in the Oxford Union style on the matter of anonymity on the internet
The Chamber proposes virtual spaces platforms should require documentation verifying actual identity when users register accounts.
John OConner for the proposition versus Mist in opposition
This will be a rational and measured debate to highlight the pros and cons of each side of the argument. Put away the (figurative) debate brass knuckles and the acrimony to participate in reasoned and civil discourse. Lincoln and Douglas would be proud.

Seasons in the Solar System
2025-02-01 10:00 - 11:00 | Auditorium
Title: SEASONS IN THE SOLAR SYSTEM
Presenter: Phil Youngblood, PhD
January is one time of the year when we most notice Earth’s seasons, but this phenomenon raises a lot of questions that are interesting to explore, such as:
— What is a season?
— What factors create seasons or affect how different the seasons are over the course of the year?
— Why does it get colder or hotter after the solstices, when the days are getting longer or shorter?
— How are seasons experienced by people and other living things in different parts of the Earth?
— Have seasons been the same over the history of the Earth? Will seasons continue on Earth into the far future?
— Do other planets or moons in the solar system experience seasons? How does this affect what we see from Earth or what someone would experience living near or on them?
— What would make us suscept that extraterrestrial planets have seasons? How might this influence whether or not there could be life there?
Join us to learn about what we know about seasons, contribute what you know or what you would like to know, and perhaps learn something you did not know about this fascinating topic!

Agrobacterium - The biography of a natural genetic engineer
2025-01-25 10:00 - 11:00 | Auditorium
Agrobacterium tumefaciens is the model organism of choice for plant genetic engineers for the better part of the plant biotechnology revolution. For this talk, I want to take you all on a remarkable journey through time chronicling the biography of this unassuming “natural genetic engineer” and how it aids the research of the genetic transformation of plant cells. Our journey will traverse a timeline of over 50 years, and will throw light on the scientific contributions from laboratories around the globe, including the stories of legendary scientists and their groups from across continents. The scientists in our story represent a diverse array of Life Science disciplines, from the traditional plant pathology, microbiology, and chemistry to evolved fields of excitement and excellence such as molecular biology, plant tissue culture, and plant metabolic chemistry.
What I hope to illustrate in my exciting story is how scientists across the world investigating Agrobacterium found intellectual eureka moments in the emergent field of plant molecular biology while birthing, nurturing and growing the field of plant recombinant DNA technology.

Playing God: How Selenium Nanoparticles Change Plants, Heal People and Protect Nature
2025-01-18 10:00 - 11:00 | Auditorium
Presented by Anton Shiriaev Ph.D.
Around one billion people on Earth lack Selenium (Se) in their diet. In severe cases, Se deficiency causes diseases and disorders in humans. Se is not essential for plants, however, they metabolize toxic Se forms from the soil into bioavailable organic molecules. Consuming fruit and vegetables enriched with Se is one of the ways to overcome or prevent dietary deficit.
We engineered three strategies allowing enriching tomato fruit with Se: plant foliar spraying, vacuum infiltration and passive immersion. Additionally to traditional methods, we introduced the application of Se nanoparticles, produced chemically or created by tiny microbes (Stenotrophomonas maltophilia). We discovered that Se, besides elevating the nutritional value of tomatoes, triggers molecular machinery resulting in better fruit quality, and potentially prolonged shelf-life.
Come to explore with us
Why Selenium used to be called an “essential poison”?
What does Selenium have in common with cuckoo birds?
Why to design better tomatoes, our research group have dared to play God three times?
