Why are Solar Storms being ignored? @DrJohnDev

Dr John Solar flares, coronal mass ejections, and super flares have the potential to significantly disrupt our power and internet infrastructure. This video breaks down the causes of these events on our sun, and evaluates the current safety mechanisms in place with the internet’s submarine fiber network. Although equipped to handle most moderate solar events, the internet has yet to be sufficiently stress tested for a major solar event.

How prepared are we and how strong can these events be?

Drawing on recent studies and historical evidence, this video challenges conventional assumptions about the severity of solar events and emphasizes the need for more proactive measures to mitigate their impact. As Earth approaches the solar maximum, the importance of awareness and preparedness in safeguarding against future solar storms cannot be understated.

By the end of this video, you’ll have a better understanding of our sun, and the impacts solar events can produce here on Earth.

Flat Earth Vs Globe Debate [ROUND 2] | Dave Weiss (DITRH) & Nathan Thompson Vs Dr. John

Dr John 2024-08-16 | Second round debate on Flat Earth versus the Globe Model of Earth with guests Dave Weiss (DITRH) and Nathan Thompson representing Flat Earth and Dr. John representing the Globe Model of Earth.
If you missed the previous debate, a link can be found here 👇
youtu.be/CDf2fOWn06M
This discussion attempts to correct many misconceptions held by the Flat Earth community, including misunderstandings of Gravity, fundamental force mechanisms, taking spectroscopy measurements, power output of stars, and historical context of the development of the Globe.
This channel does not support the Flat Earth. However, these discussions demand critical thinking of science, and many physical phenomena pointed out by Flat Earthers are interesting observations. And despite the claims made by the opposing parties, all phenomena have firm answers grounded in the current theories of modern physics. The idea of Earth as a sphere was a radical idea around 2200 years ago, but an overwhelming number of observations and data support the theory of the globe today. As with the previous debate, it is imperative to investigate these topics for yourself. It is the hope that these discussions will trigger you to investigate the answers to these questions and understand the science for yourself.
🌎Full video COMING SOON on the history of how we know the Earth is a globe. 🌍

The Flat Earthers:
David Weiss (Flat Earth Dave) is one of the leading and most outspoken advocates of Flat Earth. Dave runs theflatearthpodcast.com and appears in many Flat Earth Debates on YouTube. He is featured in the 2023 film “Level with Me” and has been highlighted by several national media networks, such as CNN & Info Wars, for his stance on Flat Earth. Dave’s YouTube Channel can be found here: www.youtube.com/@DITRHDAVE
Nathan Thompson also leads one of the largest Flat Earth communities, and has appeared in multiple films on the topic, including the 2018 Netflix documentary, “Behind the Curve”, and the 2019 film, “What If the Earth Is Flat?”. He is active on TikTok (tiktok.com/@therealnathanthompson) and runs the Flat Earth Globe Discussion on Facebook (facebook.com/groups/FlatEarthGlobeDiscussion/).

UNCENSORED Flat Earth Vs Globe Debate | Dave Weiss (DITRH) Vs Physicist Justin Woods

Dr John 2024-07-26 | Debate on the Flat Earth Model versus the Heliocentric Globe Model of Earth with special guests Dave Weiss (DITRH) representing Flat Earth and Physicist Dr. Justin Woods representing the Globe Model of Earth. While this channel is not in agreement with the Flat Earth Model, there are many arguments put forth by the Flat Earth Community that demand critical thinking and refinement in our own thinking on the science explaining Earth. These debates highlight the struggle faced by the original thinkers of the spherical Earth model, and it is important to understand why the Earth must be a sphere. Common debate strategies employed by the Flat Earth Community employ false equivalencies, hyperbole, and unclear visuals. There are explanations for each of the phenomena discussed during the debate, and it is imperative to investigate these topics for yourself.

Physicist explains quantum mechanics | Solving many-body quantum on a computer: Dr. Jon D’Emidio

Dr John 2024-06-22 | Interview with Quantum Physicist Dr. Jon D’Emidio on the weirdness of quantum mechanics, its origins, quantum entanglement, quantum spin, and the complexity required to simulate a many-particle quantum system on a computer. We begin with an “explain like I’m five” explanation of the most basic building blocks of quantum theory and then progressively build on the fundamentals required for understanding Jon’s research on large-scale quantum systems using Quantum Monte Carlo Simulations. We also discuss the current status of quantum computing, and how it is changing the landscape of quantum research. We conclude with a discussion on the ever-growing sphere of quantum pseudoscience and methods for distinguishing between legitimate quantum research and ‘quantum woo.’

🙊 Errata🙊
A few corrections to some spoken inaccuracies have been brought to my attention:

1) It was incorrectly stated photons have spin 0. Photons are considered spin-1 gauge bosons. The point remains the same, that is, the spin of photons is distinct from that of electrons.

2) It was stated that the Stern-Gerlach experiment used Nickel atoms. The Stern-Gerlach experiment was conducted using Silver atoms. Here's an excellent video on the Stern-Gerlach experiment:

Strange Quantum Reality #entanglement #reality #shorts

Dr John 2024-06-15 | This is a short clip from my full length video "Entangled Quanta v137." Video envisions humanized quantum particles, faced with the stark reality of creation and annihilation out of existence. Full description below:

The quantum theory of fields is one of the most perplexing theoretical frameworks known to civilization. The quantities computed by quantum field theory are among the most precise and accurate of any scientific theory. But particle excitations from the vacuum have perplexing implications about our reality, and what is really going on at a fundamental level.
This music video captures just some of the strangeness associated with the quantum world and allowed vacuum fluctuations. Humanizing entangled particle/antiparticle pairs coming in and out of existence while desperately trying to make sense of their reality. While the exploration is strange, it’s somehow not quite so different from our own concept of reality, perception, and what it means to be living in this universe.
What are your thoughts on your own reality?

Can Solar Storms Collapse our Power Grid? | NOAA Space Weather Prediction Center: Shawn Dahl

Dr John 2024-05-03 | Interview with NOAA Space Weather Prediction Center’s Shawn Dahl on space weather, solar super storms, solar flares, coronal mass ejections, and radio bursts. Our conversation details how solar activity is currently being monitored at SWPC, and the protocols put in place for avoiding massive disruptions to our electric power grid during a solar super storm. Impacts of historical storms are also discussed, including the 2003 Halloween Solar Storms, the March 1989 geomagnetic storm over the northeastern United States and Canada, the 1859 Carrington Event, and a recent radio burst back in December of 2023 during our current solar cycle. We’ll also discuss measures you can take for learning and preparing for the next solar super storm.
_
Shawn Dahl is a space weather forecaster with NOAA's Space Weather Prediction Center in Boulder, Colorado. He's been with the Space Weather Prediction Center for 9 years, where he also actively participates in educational outreach on space weather and how it affects us here on Earth. He served in the United States Air Force for 22 years in the intelligence and meteorology operations’ fields. After retiring from the Air Force in 2007, he served as a meteorological technician for the National Weather Service as well as the lead weather forecaster for the U.S. Air Force. In 2018, Shawn was recognized by the National Weather Service as a National level Cline Award winner.

By the end of this video, you’ll have a better understanding of our current levels of preparedness, how to interpret solar data and warnings, and the practical measures taken for handling solar events felt here on Earth.

How Total Solar Eclipse in 2024 Happens

Dr John 2024-02-17 | How are Total Solar Eclipses Predicted?

And why on April 8th 2024?

In this video, we will use real lunar data and determine how it can be used to predict the Total Solar Eclipse over the continental United States on April 8th, 2024. In order to achieve this, we need to understand the key dynamics of the Earth, Sun, and Moon system. And while most of us are familiar with these astronomical bodies, there are many subtitles between the moon’s orbit around Earth, the phases of the moon, and Earth’s orbit around the Sun that must align. And by using real lunar data, you’ll see exactly how each of these components contribute to forming the Total Solar Eclipse. The analysis performed in this video can be applied to any year or time period for predicting total solar eclipses.

By the end of this video, you’ll know why total solar eclipses are so rare, and the steps needed for determining exactly when they will occur.

Can you solve the bird train riddle?

Dr John 2023-12-16 | Can you solve this classic bird train riddle? 🚂🦅🚂

This mathematical riddle was famously posed by Max Born to his closest friends and colleagues, which included Nobel Laureates such as Albert Einstein, Marie Curie, Niels Bohr, and Erwin Schrödinger.

Surprisingly, none of them were able to figure this problem out very quickly.

The first scientist to quickly solve the problem in his head was John von Neumann.

The problem appears to be a simple 1D motion, mechanics problem on the surface, but becomes quite unwieldy when approached using a direct calculation method.

In this video, we run through the two methods that can be used to solve this problem. The more difficult method requires the use of a Geometric Series to solve the problem. But the easier approach requires only a couple lines of algebra.

We’ll cover both approaches in this video ✅

Here's a general outline:

I. Introduction of Bird Train Riddle: 0:01 |How far does the bird travel before the trains collide?
II. Background of Bird Train Riddle: 1:22 |The backstory of Max Born, John von Neumann, and the famous encounter with this riddle.
III. John von Neumann’s Method to Solving the Riddle: 3:47 |How to solve the riddle using a geometric series.
IV. Max Born’s trick to Solving the Riddle: 16:09 |How to solve this riddle quickly using a physics perspective.
V. Final Thoughts on Thought Experiments: 17:25 |Some deeper takeaways from solving thought experiments and their impact on the development of science.

Physics Reveals How the Pyramids were Actually Built

Dr John 2023-11-18 | How were the Great Pyramids of Giza built?

And how did the Ancient Egyptians lift the massive 10 ton blocks to such great heights?

In this video, we run through the physics and actually calculate the forces involved in the construction of the Great Pyramid of Giza. The ancient Egyptians used a simple machine known as a Herodotus machine. And while simple in design, the Egyptians didn’t leave many clues behind on the exact details of this machine. By using the physics of a lever system and the geometrical considerations of the blocks in the pyramid, we can backwards engineer the design of this machine.

But even with the assistance of the machine, how much lifting power was still required to lift the heavy blocks? By the end of this video, you’ll know exactly what the ancient Egyptians needed to lift during the Great Pyramid’s construction.

Here's an outline of the video:

I. The Great Pyramid of Giza’s Size and Scale: 1:24 |How much mass is actually involved.

II. Introducing the Herodotus Machine: 3:07 |A detailed animation showing the design and operation of the Herodotus Machine.

III. The Physics of a Lever System: 5:44 |All the physics of lever systems, torque, and counterweights needed to perform the calculation.

IV. Analysis of the Herodotus Machine: 10:23 |Applying the physics from part III to lifting a 10 ton block with the Herodotus Machine.

V. Geometrical and Operational Limits of the Herodotus Machine: 15:53 |In order for the Herodotus Machine to operate, certain geometrical considerations need to be applied to the blocks used in the great pyramid of Giza.

VI. Final Thoughts: 20:34 |My final thoughts on this Egyptian engineering marvel.

How the Forgotten Tech of the Pyramids Influenced the World Today #shorts #ancient #history

Dr John 2023-10-27 | Ever wonder how the Egyptians built the pyramids without modern machines? 👽🤣

Documented by the historian Herodotus and later elaborated on by the genius Leonardo Da Vinci, the Egyptians used a lever-system that incorporated a counterweight. The Herodotus machine cleverly positioned the fulcrum of the lever slightly offset from the block’s center of mass. In this way part of the block’s own mass was used as a counterweight. This ancient device utilized the mechanical advantage of using counterweights and forever changed the course of history.

In the Middle Ages, the concept of counterweights evolved and found its way into siege weaponry, particularly the formidable Trebuchets. These powerful machines could launch a flaming 200-pound projectile nearly 1,000 feet away, playing a pivotal role in the crusades in Europe and the Mongol Invasions in China.

Fast forward to modern times, and counterweights have become indispensable in various aspects of our lives. A few examples include drawbridges, construction cranes, stabilizing skyscrapers, and even the crankshafts of car engines. The Egyptians were truly ahead of their time, and their technological innovations continue to influence our world today.

If you want to learn more about this often-overlooked, silent technology, be sure to stay tuned for my upcoming video. I’ll work through the specific physics and mathematical details of the mechanical advantage of lever systems incorporating a counterweight. We’ll also see just how much force the Egyptians would have needed to provide using a Herodotus machine.

Subscribe to my channel to catch that upcoming video, and let me know if you think of more examples of counterweights used in society at large.

Where the Manhattan Project all Began⚛️🔬☢️ #shorts

Dr John 2023-07-23 | ⚛️🔬☢️💥
This was the letter written by Albert Einstein (drafted by Leo Szilard) informing President Franklin D. Roosevelt of the enormous threat a nuclear bomb posed on the Allies in World War II. German scientists Otto Hahn and Fritz Strassmann discovered nuclear fission in December of 1938, and the Nazis had already seized mines in Czechoslovakia containing vast quantities of uranium - the fissile material required for building a bomb. This letter to FDR is what set off the alarm bells that would eventually lead to the formation of The Manhattan Project. Robert Oppenheimer was eventually assigned as the director of the Los Alamos Laboratory, the final assembly and design site of the first atomic bomb.
👀This is a teaser trailer for my full-length video coming on the physics behind Oppenheimer and the Manhattan Project.

Unleashing Kinematics: Space Shuttle vs Lamborghini! Which accelerates fastest?

Dr John 2023-07-08 | 💥💥👩‍🚀🚀🆚 🏎️💪💥💥
Applying kinematics to real-world problems can be as hard as rocket science. But it doesn’t have to be that way. We're diving into the fascinating world of rocket science and determining how to apply kinematic equations to a real out-of-this-world problem: the launch of a rocket ship! 🌌🚀
But wait, there's more! We'll also compare the acceleration of the rocket ship to the newest model of the Lamborghini Revuelto. Buckle up and get ready for an epic race between rockets and supercars!
In this video, we'll start by exploring the launch of the space shuttle Discovery on July 4th, 2006. This iconic American spacecraft completed a staggering 39 launches, orbited the Earth 5,830 times, and traveled a mind-boggling 149 million miles! To reach orbital speed, the shuttle had to accelerate its 78 metric ton body to a mind-blowing speed of 17,500 miles per hour or over 7800 meters per second. And it accomplished all of this in a mere 8 and a half minutes!
But finding the rocket's acceleration isn't as simple as dividing its change in velocity by the launch time!
Here’s an overview of what we cover:
🚀The Anatomy of NASA’s Discovery Orbiter: What it takes to get 78 metric tons into orbit.
📈The Velocity vs. Time of the Discovery Orbiter’s Launch on July 4th, 2006

Master the Top 3 Kinematic Equations for Solving Motion Problems!

Dr John 2023-07-08 | ✍️👨‍🔬1️⃣✅2️⃣✅3️⃣✅💯💯
🚀 Welcome back, fellow learners! In today's derivation video, we dive deep into the top 3 kinematic equations you need to conquer any motion problem with constant acceleration. Whether you're a physics enthusiast or a student striving for academic excellence, this knowledge will be key for using these equations appropriately.

🔬 Join me, John, your friendly physics guide, as we demystify the common kinematic equations on my channel @DrJohnDev. Don't forget to hit that subscribe button and unleash your inner curiosity!
🌍 Kinematic equations hold immense practical value, applying to various scenarios, including objects in free fall near Earth's surface. But let's be clear—constant acceleration doesn't mean all objects accelerate at a steady rate in every situation. Understanding their limitations is important!
💡 Why opt for constant acceleration? By making this assumption, we drastically simplify the calculus-based relationships between displacement, velocity, and acceleration into nicely packed algebraic expressions. These powerful equations are collectively known as the Kinematic Equations.
Here’s an outline of the video:
📚 Derivation of the first kinematic equation using the time-derivative definition between velocity and acceleration.
🔍 Unraveling the second kinematic equation using the time-derivative definition between displacement and velocity.
⚡ Delving into the third and often overlooked kinematic equation, which expresses velocity as a function of displacement.
🎓 Armed with these three powerful equations, you become an unstoppable force in solving kinematics problems with constant acceleration. Stay tuned for our next video, where we tackle real-world examples and delve into scenarios where these equations shine and others… where they might not apply.

Mind-Blowing Kinematics: Unveiling the Secrets of One-Dimensional Motion! Watch Mario Interrupt!

Dr John 2023-06-17 | 🚗🚗🚂🚂🚂✈️🚀🚀🚀🚀
Need help understanding the fundamentals of motion? 😱 Or need help plotting motion graphs for displacement, velocity, and acceleration?

In this video, we review the definitions and concepts of distance, displacement, speed, velocity, instantaneous velocity, and acceleration. We review the subtle differences between the scalar quantities of distance & speed and the vector quantities of displacement, velocity, and acceleration. We also highlight how they’re related using their slope definitions and relationships in calculus.

We also cover the motion-graphs of these quantities and how to plot each one versus time. We again highlight the calculus relationships between each quantity of motion and how to derive each one given the other.
We covered a few real-world examples to help with illustrating these concepts:

🗺️For distinguishing between distance and displacement, we took a hike up the Pacific Crest Trail (PCT). For more information regarding the PCT, visit the official Pacific Crest Trail Association website at:
pcta.org

📈For illustrating the motion graph plots, we took a ride on Amtrak’s Lake Shore Limited Route from Chicago to New York. For more information on this train route, visit Amtrak’s official website at:

Dimensional Analysis: Intro to Pro

Dr John 2023-04-09 | Need a starting point in your physics class? Not sure where to begin? Or are you an experienced student in science and engineering
and wanting to learn a simple trick for building your problem solving confidence and test-taking ability?

In this video, Dr. John introduces the problem-solving technique of dimensional analysis, which is often overlooked in introductory
physics classes but is highly valuable throughout all branches and course levels of physics. By using this technique, you can develop
your physics intuition, understand concepts more clearly, contextualize bigger picture ideas, and improve your test-taking abilities.
Dr. John explains the importance of units in science and engineering and introduces the International System of Units (SI), which includes
seven fundamental base units and 22 derived units. He provides an example of Newton's 2nd Law and how dimensional analysis can be used
to determine the units of force. He builds intuitive examples of common human-scale metric units. The power of dimensional analysis is
then demonstrated in 3 key examples. First, it is used to find the units of the force constant in Newton’s Universal Law of Gravitation.
Second, dimensional analysis is used to narrow the choices of a multiple choice question asking for the correct expression for a pendulum's period.
Finally, as a last challenge, dimensional analysis is used to determine the exponents in the drag force expression for Stokes’ Law.
Overall, this video provides viewers with a foundational understanding of dimensional analysis and how it can be applied to a large array
of scientific contexts.
