A consequence of the Big Bang theory is the evolution of the universe over time. By examining galaxies with different redshifts, astronomers are able to “look back in time” and obtain data regarding the shape, size, and distribution of galaxies throughout the history of the Universe. The observations made indicate that the trends followed by stars, galaxies and clusters are much different from those we currently see, providing further evidential support for the Big Bang. Evolution of Galaxies The shape of galaxies 14 billion years, 9 billion years, 5 billion years, and 2 billion years from left to right after the Big Bang. Surveys of distant, highly redshifted galaxies indicate that in the past galaxies were generally smaller and more irregularly shaped than those of the present age. Notice how galaxies dating from 2 billion years after the Big Bang are irregular and blob-like, while those from 9 billion years and onward are more regular spirals. Occasionally the gravitational attraction between galaxies can cause two galaxies to collide. While individual stars rarely slam into each other during such collisions, the tidal forces caused by dramatic shifts in the gravitational field will often reshape and deform the galactic structure. Observations show that primordial galaxies were much more likely to undergo such interactions. Some collisions would result in the merging of small irregular galaxies to form larger spiral or elliptical structures.

The Universe in One Year was inspired by the late astronomer, Carl Sagan (). Sagan was the first person to explain the history of the universe in one year-as a “Cosmic Calendar.
Geologic Time, Geologic Processes Past and Present – Uniformitarianism And it seems like the time when after doubt Oh, never this whelming east wind swells But it seems like the sea’s return To the ancient lands where it left the shells Before the age of the fern; And it seems like the time when after doubt Our love came back amain. Oh, come forth into the storm and rout And be my love in the rain. We are reasonably adept at manipulating the physical world in terms of spatial relationships and physical parameters temperature, pressure , but one dimension of the physical world has so far escaped our manipulative powers TIME.
The time traveler’s machine from the ‘s George Pal adaptation of the H. Wells classic “The Time Machine”. Time is comprehensible to us as long as we can track it in terms of seconds, minutes, hours, days, and years, but once we go beyond the realm of our own time experience, our perception tends to get fairly vague. For example if I were to ask when Napoleon [ ] was born, I would be lucky to get an answer like “sometime in the middle of the 18th century”.
We basically have trouble to visualize time intervals that are significantly larger than our own lifespan. Time is a very important variable in geology, because the exact timing of spatially separated events allows us to reconstruct the surface and surface conditions of the ancient earth. It also allows us to put events into chronological order and by those means to deduct the driving forces behind the continual changes of the Earth.

Lab 2 should be part of your notebook We then worked on an assignment exploring the Panamanian land bridge That means it’s also time for a notebook check. The list of items to be graded is posted evey day in class. Sept 27 Students did an activity, learning about the interactions between 5 of Earth’s “spheres.
New federal exercise recommendations include the first-ever federal activity parameters for 3-year-olds, as well as a few surprising omissions.
In episode 2, Mai wins at the stair-climbing game by reciting a password from the original Dragon Quest I. Later in the episode, she’s actually trying to play Dragon Quest, only to realize she misremembered the password and can’t start her game. At the beginning of Episode 8, Nano accidentally activates a Rocket Punch. Her right hand then flies across the sky during Sasahara’s segment causing him to write a haiku about it , and comes back again later to sock Misato in the head.
And at the end of the episode we see Misato cooking at home, with a bump from the head injury she got earlier visible. It’s also the primary reason why there’s no rock-paper-scissors segment that week – that’s her rock-paper-scissors hand. Right in the first episode there’s the objects that go flying in the explosion at the start and, more significantly, the poor boy who only shows up atop a chimney at the end of the episode when you’ve forgotten all about him. At the very beginning of the next episode, the boy walks in front of Mio, Yuuko and Mai as they play the stair game, showing he did, in fact, get down.
In Episode 22, Misato’s little sister tries to hit Mio’s big sister with a shinai, only to accidentally hit the assistant kendo instructor who just happened to appear at the right moment , knocking him off of the bicycle he was riding. Later, when Fecchan tries to make the best of having dropped her ice cream by claiming that she can still eat it after cleaning it off, the bike and the instructor come by and ruin what was left of her ice cream.
In Episode 25, while Ms. Nakamura is walking down the street, the bike is incredibly, still continuing its path without the rider. However, the manga chapters these two skits were based on were consecutive; still, to bother animating the bike at all A dorayaki Tanaka pulls out of his afro for Sakurai-sensei resurfaces in an appropriate ‘Short Thoughts’ segment later on.
Central Nervous System: Definition, Function & Parts
Confirmation of Stellar Evolution Models Star clusters provide us with a lot of information that is relevant to the study of stars in general. The main reason is that we assume that all stars in a cluster formed almost simultaneously from the same cloud of interstellar gas, which means that the stars in the cluster should be very homogeneous in their properties. This means that the only significant difference between stars in a cluster is their mass, but if we measure the properties of one star age, distance, composition, etc.
In reality, some stars in the cluster form earlier than others, but compared to their lifetimes, the spread in their formation times is small and can be ignored.
Biological evidence of the age of the earth includes radioactive dating of rocks, fossil evidence, comparative anatomy and molecular clocks. Most scientists think there is lots of evidence to prove that the earth is billions of years old.
June 16, When the universe was just of a second or so old — that is, a hundredth of a billionth of a trillionth of a trillionth of a second in age — it experienced an incredible burst of expansion known as inflation, in which space itself expanded faster than the speed of light. During this period, the universe doubled in size at least 90 times, going from subatomic-sized to golf-ball-sized almost instantaneously.
The work that goes into understanding the expanding universe comes from a combination of theoretical physics and direct observations by astronomers. However, in some cases astronomers have not been able to see direct evidence — such as the case of gravitational waves associated with the cosmic microwave background, the leftover radiation from the Big Bang. A preliminary announcement about finding these waves in was quickly retracted, after astronomers found the signal detected could be explained by dust in the Milky Way.

Game Reviews Free Classroom Posters I’ve created this special page on my blog to house all of the posters I have created for my classroom over the past few years. I have made them free for you to download and use in your own classroom as a way to say thank you to the thousands of people I’ve stolen teaching ideas from on the internet. For each poster, I have tried to provide a PDF copy and an editable copy.
The PDF copy preserves my font choices, but you cannot edit it. If you download the editable copy, the fonts will change unless you have fonts I used installed on your computer. Almost all of the fonts I use can be downloaded from Font Squirrel. I teach high school math, but teachers of other subjects and grade levels should be able to find some useful posters as well for their classrooms.
The majority of these posters are made to print on letter sized paper. I often print these on colored cardstock and laminate for extra durability. This lets me reuse the same posters from year to year. Though, if you look at my classroom pictures, you will realize that nothing tends to stay in the same spot. And, plenty of other posters get rotated in and out.
Earth Science with Lab
Engineers Explained People who work in the fields of science and technology are not like other people. This can be frustrating to the nontechnical people who have to deal with them. The secret to coping with technology-oriented people is to understand their motivations. This chapter will teach you everything you need to know.
I learned their customs and mannerisms by observing them, much the way Jane Goodall learned about the great apes, but without the hassle of grooming. Engineering is so trendy these days that everybody wants to be one.
In this lesson, you will learn about the structure, function, formula and importance of glutamic acid. At the end of the lesson you can check your understanding by taking a short quiz.
Buy from another retailer: I am not an expert in love. What I am, however, is a mathematician. My aim in writing this book is not to replace any of the other excellent sources available on the science of human connection. Instead, I want to try and offer you a different perspective on the most talked-about subject in the history of human existence, using mathematics as a guide.
Because mathematics is ultimately the study of patterns—predicting phenomena from the weather to the growth of cities, revealing everything from the laws of the universe to the behavior of subatomic particles. And if we consider them honestly, none of those things is neatly ordered or easily predictable, either. Thankfully, love—as with most of life—is full of patterns: These patterns twist and turn and warp and evolve just as love does, and are all patterns which mathematics is uniquely placed to describe.

There are four forces of nature. Two are familiar to everyone; two are less so. First, gravity is the force that pulls us to the surface of the Earth, keeps the planets in orbit around the Sun and causes the formation of planets, stars and galaxies. Second, electromagnetism is the force responsible.
Filed under Pagadian City The Philippines, being a country archipelago of islands and seas, have naturally wonderful beaches, some of which are famous the world over. Beaches like Puerto Galera, Boracay, and the various beaches in Cebu rake in tourists from around the world all year round because of their pristine and cool blue waters and fine, white-sand shores.
However, if one will just look around more, they will find that there are other less-known but equally beautiful beach spots in other parts of the Philippines. In Pagadian, in particular, there are beaches and islands that will make one believe that there is such a thing as a secluded paradise on Earth. A nice place to start would be the Dao-Dao Islands some seven to ten minutes away from the seaport, when riding a motorboat. It is a rather big island, with an area size of about 1.
The coral reefs are artificially made, but the whole place is very much ideal for swimming, fishing, and boating. During low tides, a smaller, more undeveloped island appears and like the rest, is also suitable for fishing and swimming. There is also the White Beach that, as its name suggests, is a stretch of white sand beach just minutes southeast of the seaport.
Again, it can be reached via motorboat.
7 Tips for Dealing With Rejection
Have you ever wondered how we know so much about the universe? Learn about how we use technology to study the universe, from the tiny to the enormous. Then take a quiz to test your knowledge. But we’ve also seen an incredible acceleration in human knowledge over the last years compared to thousands of years before that. Thanks to technology, we’re able to study the universe so much more easily than we once did, and to a greater level of detail. Across many fields of study, we try to understand the universe on a very large scale or on the microscopic level.

The sexagesimal method developed by the Babylonians has a far greater computational potential than what was actually needed for the older problem texts. With the development of mathematical astronomy in the Seleucid period, however, it became indispensable. Astronomers sought to predict future occurrences of… The scope of astronomy Since the late 19th century astronomy has expanded to include astrophysics , the application of physical and chemical knowledge to an understanding of the nature of celestial objects and the physical processes that control their formation, evolution, and emission of radiation.
In addition, the gases and dust particles around and between the stars have become the subjects of much research. Study of the nuclear reactions that provide the energy radiated by stars has shown how the diversity of atoms found in nature can be derived from a universe that, following the first few minutes of its existence, consisted only of hydrogen , helium , and a trace of lithium. Concerned with phenomena on the largest scale is cosmology , the study of the evolution of the universe.
Astrophysics has transformed cosmology from a purely speculative activity to a modern science capable of predictions that can be tested. Its great advances notwithstanding, astronomy is still subject to a major constraint: Almost all measurements must be performed at great distances from the objects of interest, with no control over such quantities as their temperature , pressure , or chemical composition.
There are a few exceptions to this limitation—namely, meteorites most of which are from the asteroid belt, though some are from the Moon or Mars , rock and soil samples brought back from the Moon , samples of comet and asteroid dust returned by robotic spacecraft , and interplanetary dust particles collected in or above the stratosphere.
These can be examined with laboratory techniques to provide information that cannot be obtained in any other way.
End of the Universe?
Introduction Does God Exist? The reality of God’s existence is the most important question, since it has eternal consequences. The evidence for God’s existence comes primarily from the design of the universe. It is virtually impossible that all the physical laws would just happen to be tightly constrained by chance in order for stars and galaxies to exist. Rich Deem Part 1 of the introduction for non-believers showed that strong atheism contradicts its own worldview by believing the universe has a natural cause despite the lack of observational evidence for such a belief.
There is a longing in each of us to understand the meanings of symbols and messages, to remember the sublime language of a Universe that speaks in a myriad of symbols ~ it seems to connect us to who we truly are, to be at one with all of the energies of the Universe.
Manassas, VA Usage of the state seal to illustrate this site does not indicate that this is an official state site. The standards emphasize historical contributions in the development of scientific thought about the Earth and space. The standards stress the interpretation of maps, charts, tables, and profiles; the use of technology to collect, analyze, and report data; and the utilization of science skills in systematic investigation.
Major topics of study include plate tectonics, the rock cycle, Earth history, the oceans, the atmosphere, weather and climate, and the solar system and universe. The Earth Science standards continue to focus on student growth in understanding the nature of science. This scientific view defines the idea that explanations of nature are developed and tested using observation, experimentation, models, evidence, and systematic processes. The nature of science includes the concepts that scientific explanations are based on logical thinking; are subject to rules of evidence; are consistent with observational, inferential, and experimental evidence; are open to rational critique; and are subject to refinement and change with the addition of new scientific evidence.
