30,000 years from now, Niagara Falls will have eroded the remaining 32 km to Lake Erie and will cease to exist.
100,000 years from now, the proper motion of stars across the celestial sphere, which results from their movement through the Milky Way, renders many of the constellations unrecognizable.
500,000 years from now, Earth will likely have been hit by an asteroid of roughly 1 km in diameter, assuming that it cannot be averted.
1 million years from now, Betelgeuse will have exploded in a supernova, making it visible on Earth in daylight.
50 million years from now is the earliest estimated time for Earth to naturally replenish its fossil fuel reserves.
180 million from now, due to the gradual slowing down of Earth's rotation, a day on Earth will be one hour longer than it is today.
250 million years from now, the west coast of North America, the coast of California will collide with Alaska.
1.2 billion years from now is the high estimate until all plant life dies out.
2 billion years from now is the first close passage of the Andromeda Galaxy and our Milky Way galaxy.
5.4 billion years from now, the sun begins to evolve into a red giant, engulfing the Earth and moon.
150 billion years from now, the Universe's expansion causes all galaxies beyond the former Milky Way's Local Group to disappear beyond the cosmic light horizon, removing them from the observable universe.
1 trillion years from now, star formation ends in galaxies as galaxies are depleted of the gas clouds they need to form stars.
120 trillion years from now, stars in the universe will have exhausted their fuel.

How Many Faces, Edges And Vertices Does A Sphere Have?
Here we’ll look at how to work out the faces, edges and vertices of a sphere.
We’ll start by counting the faces, these are the flat surfaces that make the sphere. A sphere has 0 faces altogether - but it does have a curved surface.
Next we’ll work out how many edges the sphere has, which are where two faces meet. A shere has 0 edges.
Next we’ll count the corners of the sphere (the corners). No surprises, a sphere does not have any vertices.
For the full playlist for the faces, edges and Vertices of a whole lot of 3D shapes go to https://www.youtube.com/playli....st?list=PLjbxBzUM6SL

Today is July the 3rd. And for us humans on earth, today is the day that we're the furthest away from the sun that we’ll be all year. So why is it so warm? Where I live, it's summertime and we've just gone through our first heatwave of the year, and you'd think it would be cold when you're far away from the sun and warm when you're close to the sun. On the 3rd of January. But it's the other way around. This can all be explained by the fact the earth has a tilted axis like my head. Right now, in the summer, we're tilted towards the sun, so we're getting more heat from it. Just to give you some concrete numbers. We're getting about 7% less energy from the sun by being far away now compared to January the 3rd, when we're closer, we get 7% more. But the difference in tilt means tilting towards the sun gives about 500 percent as much energy as being tilted away. For here in London. It obviously varies depending on how high up or down in latitude you are. And obviously everything's flipped for the southern hemisphere because it's their winter at the moment, so it does kind of make sense for them. But it's interesting. This combination means that in the Northern Hemisphere we have slightly longer summers and slightly shorter winters, whereas in the southern hemisphere it's the opposite way around. They have slightly shorter summers and slightly longer winters. So in conclusion, as they always say, nobody cares how far away you are from the sun. If you've got a wonky axis.

Linear Algebra on Khan Academy: Have you ever wondered what the difference is between speed and velocity? Ever try to visualize in four dimensions or six or seven? Linear algebra describes things in two dimensions, but many of the concepts can be extended into three, four or more. Linear algebra implies two dimensional reasoning, however, the concepts covered in linear algebra provide the basis for multi-dimensional representations of mathematical reasoning. Matrices, vectors, vector spaces, transformations, eigenvectors/values all help us to visualize and understand multi dimensional concepts. This is an advanced course normally taken by science or engineering majors after taking at least two semesters of calculus (although calculus really isn't a prereq) so don't confuse this with regular high school algebra.

I’m guessing you’re pretty familiar with ice. We use it in our drinks, slip on it, skate on it, worry about climate change melting it. But have you ever stopped to really think about this stuff? The freezing and melting of water affects so much of our world. It’s ice crystals in thunderclouds that create lightning. Ice is powerful enough crack boulders, float stones, and alter entire landscapes. Ice is such a common substance, you'd think we'd know everything about it by now. But it has some secrets and weird properties we’ve only just begun to figure out. One question about ice that's, still not totally answered, is one of the most obvious: why is ice slippery? It's a more complicated answer than it seems!

Linear Algebra on Khan Academy: Have you ever wondered what the difference is between speed and velocity? Ever try to visualize in four dimensions or six or seven? Linear algebra describes things in two dimensions, but many of the concepts can be extended into three, four or more. Linear algebra implies two dimensional reasoning, however, the concepts covered in linear algebra provide the basis for multi-dimensional representations of mathematical reasoning. Matrices, vectors, vector spaces, transformations, eigenvectors/values all help us to visualize and understand multi dimensional concepts. This is an advanced course normally taken by science or engineering majors after taking at least two semesters of calculus (although calculus really isn't a prereq) so don't confuse this with regular high school algebra.
About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

Precalculus on Khan Academy: You may think that precalculus is simply the course you take before calculus. You would be right, of course, but that definition doesn't mean anything unless you have some knowledge of what calculus is. Let's keep it simple, shall we? Calculus is a conceptual framework which provides systematic techniques for solving problems. These problems are appropriately applicable to analytic geometry and algebra. Therefore....precalculus gives you the background for the mathematical concepts, problems, issues and techniques that appear in calculus, including trigonometry, functions, complex numbers, vectors, matrices, and others. There you have it ladies and gentlemen....an introduction to precalculus!

DeepSeek-R1 is a strong performing, open source reasoning model with several distilled versions that can be run locally. Here, we walk through the DeepSeek-R1 paper to review the details of the training methodology, download the 14b distilled model via Ollama, test generation / JSON-mode, and then test it in a fully local "deep research" assistant that performs web-research / summarization w/ an iterative reflection step to improve its results.
