i worte about exoplanets TOI-2095 b and TOI-2095 c and how they were obiting a near by star and how it was habitable and how it will be a back up plan for humanity .I felt that i could have wrote abit more but over all I think that the amount of work I did was pretty good. I hope that the next CCA will be on exoplants.
today i saw the other groups presentation ,one of them was about how extraterestial can help us devlop our technology and i learnt after 6 years in primary school i still have the fear of public speaking
very good i learnt about the planets
today cca was ok abit boring but at least i learned some formula ex formula with sine and cosine
ok i guess learn about the roket luanches and did a slide on it was good because it was good SPACE BALLZ https://www.canva.com/design/DAGCqOM1iZs/MwgB0Oe21YR3DdhbT6qikw/editnjo need
The universe, with its vastness and complexity, invites profound reflection. Its scale stretches from the infinitesimally small quantum particles to the boundlessly large galaxies. Central to our understanding are fundamental formulas like Einstein's equation, E=mc2, which reveals the equivalence of mass and energy, and Hubble's Law, v=H0d, describing how galaxies recede with the expansion of space. These equations underscore a universe in dynamic flux, governed by fundamental forces and principles. The cosmological constant, Λ\LambdaΛ, in the Einstein field equations of General Relativity, further illustrates the universe's accelerating expansion. Together, these formulas not only map the physical dimensions of reality but also echo the interconnectedness and harmony underlying the cosmos. They remind us of the profound beauty and mystery inherent in the universe's fabric, prompting both awe and a quest for deeper understanding.
Radio waves, a type of electromagnetic radiation, are crucial to modern communication and our understanding of the universe. These waves, with wavelengths ranging from millimeters to kilometers, carry information across vast distances. The fundamental formula for radio waves is the wave equation: v=fλv = f \lambdav=fλ, where v is the speed of the wave (approximately the speed of light in a vacuum), f is the frequency, and λ\lambdaλ is the wavelength. This relationship highlights how changes in frequency or wavelength affect the propagation of radio signals. Additionally, the formula for energy E=hf, where h is Planck’s constant, relates to the quantized nature of electromagnetic waves, including radio waves. These equations not only facilitate technologies like broadcasting and radar but also deepen our grasp of the universe's electromagnetic spectrum, revealing insights into cosmic phenomena and the fundamental nature of light itself.
Orbits, the paths followed by celestial bodies under the influence of gravity, are central to our understanding of astrophysics. The elegance of Kepler’s laws describes these elliptical paths: Kepler's First Law states that planets orbit in ellipses with the Sun at one focus. Kepler’s Second Law reveals that a planet sweeps out equal areas in equal times, illustrating the variable speed of orbiting bodies. Newton's Law of Universal Gravitation, F=Gm1m2r2F = \frac{G m_1 m_2}{r^2}, quantifies the gravitational force between two masses, where Gis the gravitational constant and rrr is the distance between the masses. This force dictates orbital motion, leading to the formula for orbital velocity v=GMrv = \sqrt{\frac{GM}{r}}v=rGM, where M is the central mass. These formulas not only describe the mechanics of orbits but also illuminate the harmonious interplay of forces that govern the celestial dance of planets and moons.
Reflecting on the universe reveals a tapestry of galaxies, each contributing to the cosmos' grand narrative. Spiral galaxies, like our Milky Way, are characterized by their elegant, rotating arms and central bulges, showcasing dynamic star formation and cosmic structure. Elliptical galaxies, often more spherical or elongated, are older and contain less active star formation, often resulting from past galactic collisions. Irregular galaxies defy conventional shapes, embodying the chaotic beauty of cosmic interactions and star birth. This diversity illustrates the universe's complex nature and the varied evolutionary paths of galaxies. Each type of galaxy adds a unique chapter to the cosmic story, highlighting both the orderly and unpredictable elements of the universe. Contemplating these diverse galaxies enhances our understanding of cosmic evolution and our place within this vast expanse, deepening our appreciation for the universe's grandeur and the mysteries that continue to unfold.
I was absent from this lesson because of the AMC, so I did not hear any of the lectures
Nuclear physics delves into the forces and particles within the atomic nucleus, offering crucial insights into the fundamental nature of matter. It has led to groundbreaking advancements in both science and technology. For example, nuclear fission powers our energy grids, while nuclear fusion holds the promise of a cleaner, nearly limitless energy source. Beyond energy, nuclear physics has significantly impacted medicine, providing tools for diagnostics and treatment, such as PET scans and radiation therapy for cancer. Additionally, this field has reshaped our understanding of the universe, revealing the complexities of quantum mechanics and particle interactions. However, nuclear physics also brings ethical challenges, particularly concerning the risks of nuclear weapons and radioactive waste. As we continue to explore its potential, nuclear physics exemplifies the dual-edged nature of scientific progress, where profound discoveries come with responsibilities that must be carefully managed.
today was fun as i learned about the universe and what it had to offer it can be improved by having more in depth stuff
today i learned about da mars da venus da gas giants da jupiter da saturn da uranus da neptune it was kind a boring but i got through it sigma trust ngl i don't see how this is gonna help me in astrolmiad
today learn about astroids and metorids which was fun but some stuff got repeated
today we did the debate thing not going to lie the discrimnat thing was pretty funny after that we saw a presentation on creted worlds which was confusing cause how was the highlands older than the mare like they said that 0.8 billion years is not alot but i still do not understand
to day we did water rokets and becuase i think it was slow i popped a bottle. after that we learned about the pluto and the moons and the rings and then we did a blooket which was fun. we can increase the range by increasing its angle. as the pressure increase the range increase
todays lesson is very fun they talked about the solar flares and solar weather with was very interesting and i would like to go for more sessions to learn more and i also learned about why they used diffrent colours to depict the sun and the effects of sloar weather on the earth and how to prevent and protect angianst it
it is very fun as it is a summary of all the things we learn basicly anything that we forgot and it was very sad for me because a dear exco member of astro does not know me and i talk to him alot and he also did not let me answer alot of questions other then that there is nothing else except for not having alot of time due to haveing issues with the air play and also i do not have access to the attendence but is ok until they made me do a google form which needed me to mark my sec3 and sec4 attendence but scince my name was not there i had to help howard and advive to check their attendence andsrry for mi spelling
it was very fun as we named the star in the simulation aka universe sand box some nuclear active waste and we name the moon hibibiamirmini87promax which sadly crashed into some nuclear active waste and after that we made a planet named habibiamir63 it was very good as it have a green glow from some nuclear active waste and i hope that some nuclear active waste can snaw and i hope that hibibiamirmni87promax gets renamed to hbbamrm87pm and that habibiamir63 gets renamed to hbbamr63
