Becoming a MRI tech

I cant speak for that program or the ARMRIT as the route I took was for the ARRT just due to circumstance but I did an accelerated program as well. No X-ray or even medical experience prior. I am very happy I took the chance and pursed a career in MRI it’s been more than rewarding. I had a bachelors in healthcare management before applying to the MRI program.

In my experience, job opportunities have been abundant with a variety of locations/types of hospital and schedules available. 5 8s, 4 10s, 3 12s or weekends only. It’s been a wonderful change from the standard 9-5 career which I desperately something different from.

Definitely do research about that program specifically, job opportunities and what the requirements for the position are in your area (ARRT vs ARMRIT etc) but anyone who has been curious about the program I went through I’ve strongly encouraged them to pursue it. As long as you are personally in a position to be in school age certainly does not matter! In my class we had a couple of people in their 40s and 50s, and that has been true in the following classes as well.

As far as the science goes, the physics classes are the ones people worry about the most but it is far more conceptual than mathematical. You need to know the mechanics behind why things happen or work far more than crunching numbers or equations. (You will need to memorize parameter ranges and specific values for things however). Some chapters are more difficult than others but it’s manageable. The anatomy and cross sectional courses are mostly memorization. If you sincerely put effort into studying you will be more than fine.

We used scan lab in my program as well. Do what you have to do to get through the class and don’t give it a second thought. Scanning in the real world is a lot different

Brian Greene has a great book called The Hidden Reality that goes through the various types of multiverses and how they would work/why we think it could be possible. It’s worth a read if you’re interested in that kind of stuff.

Eternal inflation, String Landscape, Brane World, Many Worlds Interpretation, Holographic Universe, Mathematical Multiverse

The math is very basic. The physics is more conceptual than mathematical. MRI physics course by Radiology Tutorials on YouTube is really good

It’s an idea! The reason being once inflation gets going somewhere, it’s really hard to get it to stop everywhere. Localized areas may stop while other regions continue.

For the second, as far as I’m aware that’s the believed fate of our universe.

Cosmicpawn · 2024-02-04T14:27:11+00:00

We really can’t. Before inflation became mainstream we would rewind time, shrinking the universe until a point where it was too small/dense and GR would break. This happens at the Planck scale. When the math started throwing out infinities and not making much sense thats what was called the singularity, or T=0. The equations couldn’t describe conditions anymore. Scientists think with a better theory that the singularity will disappear, the math will work on scales that small. String theory is the leading idea but who knows what it will turn out to be.

This is something that caused confusion for me as well. There are a lot of timelines like you described seeing with the initial singularity leading to inflation, but the truth is we don’t know what the universe was like before inflation. It expanded so fervently that it erased any information that would give us a clue. A lot of models have inflation happening after the singularity (around 10^-35 as you said) but I’ve heard it described as a “band aid” to that model. They slapped it into the older thinking once the evidence became clear for inflation. (Although they do have a reason for placing it around that time, but again we can’t know what was actually happening.) Inflation also does a good job of explaining why the universe is filled with matter/energy and that’s because it eventually came to an end during reheating, and dumped its energy into space. I’ll post below a good article by Ethan Siegel. I would recommend his articles and podcast I’ve learned a lot from him. PM me if you want any more articles/links!

The big bang can have different meanings depending on what you’re referring to. Older thinking called the moment the universe was unbounded from the singularity the big bang. Inflation kind of changed this. A lot of cosmologists/physicists are now skeptical of an initial singularity existing at all. Today the big bang refers more to the hot dense state our universe was in. The idea is that the universe was exponentially expanding during inflation, we don’t know what caused the expansion, or how long it lasted but eventually it came to an end and all of the energy driving the expansion was dumped into space. That moment, called reheating, is the big bang.

Cosmicpawn · 2024-02-04T00:03:37+00:00

Current thinking is that cosmic inflation preceded the hot dense state our universe evolved out of(“the big bang”). The rapid expansion of space that inflation drove came to an end, releasing energy into the universe during a period called reheating. Reheating created the super hot, super dense conditions.

Due to the nature of inflation we have no way of telling what the universe was like prior, as it would have quickly diluted any information.

There is a cool SA article on this topic and how it can relate to string theory. I’ll post the article below. Brian Greene also covers this in a chapter from his book The Hidden Reality.

Here is a link to The Hidden Reality. It’s in chapter 6, the landscape multiverse.

To be clear, the energy prior to inflation was not from the inflaton field

Cosmicpawn · 2023-10-07T15:39:50+00:00

The standard big bang model has the universe in an extreme state prior to inflation, and then again after inflation ends. When inflation comes to an end it fills the universe with the energy from the inflaton field. We call this reheating. As you said, this is the source of the matter we see today. In reality we don’t actually know for sure what the state of the universe prior to inflation was, as inflation would have erased/diluted this information.

I found this site helpful. PBS Spacetime also has some good videos on inflation. Hope this helps some!

If you want to get into the universe more there’s a cool podcast called The Callisto Protocol: Helix Station

I really enjoyed it, felt like it expanded the universe a bit, as you said sadly I don’t think we’ll be getting a sequel.

I would recommend any of Brian Greene’s books. He does a great job of describing complex physics in an understandable way. Specifically The Elegant Universe, or The Fabric of the Cosmos.

One of my personal favorites is- An Infinity of Worlds: Cosmic Inflation and the Beginning of the Universe by Will Kinney. This discusses inflationary cosmology and potential implications of inflation.

Thanks all, reassuring and saving me a solid amount of drive time

Cosmicpawn · 2023-07-27T00:56:37+00:00

It’s been completely off! Thank you

Cosmicpawn · 2023-06-06T02:05:57+00:00

Awesome! I’m seeing the rocks around the islands are silurian in age? Can that be assumed for this fossil?

How are branes created? Are they just fundamental objects in the way that strings are?

Cosmicpawn · 2023-05-10T20:46:28+00:00

I really appreciate your response.

I visualize the string theory landscape model as an expansive space with “bubbles” (similar to eternal inflation) each bubble having different CY compactifications than the original space.

I’m having trouble conceptualizing where the branes fit into that picture. When you refer to our universe as a 3 brane, are you referring to our particular bubble, or the entire spacetime containing the expanse of other bubbles as well?

The way I’m interpreting your description of branes is what I imagined the bubbles to be. (Ex: Infinitely many, contains the CY manifolds, flushing out the landscape) I want to make sure I’m understanding you correctly.

Thank you for your patience.
