I have to write anatomy journals for a class. I'm just running out of things to talk about. I just need simple daily things that have to do with anatomy to talk about. Like, "my friend broke his femur and.. " Anatomically speaking, I'm kind of boring. I've never broken anything, and I've got no cool hospital stories to write about, haha. I'm half way done with them, and I'm just out of things to write about. And I'm bored.

So if you could give me little, interesting things to write about, I'd really appreciate it. I don't mind looking things up if you just give me a name of something, and I certainly don't want yall to write anything for me. I just need topic ideas.

Thanks!

I have been having upper abdominal pain for several years off and on. The pain recently got worse and didn't go away. I've had diverticulitis in the past and had surgery for that. I was sent to have a Ultrasound of my gallbladder and it showed thickening of the gallbladder but no stones. I was then sent for a HIDA scan with CCK and my ejection rate was 0%. My medical doctor wants me to see a surgeon and get my gallbladder out but I'm supposed to start college on Aug. 15th. Does anyone know if my results indicate anything that could be dangerous? or could I put off having surgery until next summer?

What are your opinions concerning this information?

"Darwin might never have completed the book if another British scientist, Alfred Russel Wallace (1823-1913), had not come up with the same idea in 1858. While living in the Malay Archipelago in the Pacific Ocean, Wallace formulated his theory and wrote it in an essay, which he sent to Darwin. Darwin's fellow scientists persuaded him to let them present his theory and Wallace's essay jointly at a scientific meeting. The presentation excited very little attention, according to the modest Darwin."

"However, the publication of Darwin's book The Origin of Species in 1859 changed biology forever."

I just came back to studying physics after a month break, and I'm starting to get my feet wet again. I've come across a problem which I just cannot figure out. Two boxes are connected with a length of rope connecting the top of the bottom box to the bottom of the top box. There is also a rope coming out of the top of the top box. Each box is 10 kg, the mass of the strings is negligible. The boxes are accelerated upwards at 5 m/s^2. I need to find the tension in both strings.

Now, I know I should use F = ma (F = 10*5 = 50?), but I also need to incorporate g = 9.8 m/s^2... How do I do this problem? Again, I apologize for the triviality of the problem.

Step 1: get donations or buy 20-30 concrete stepping stones (2" or so thick, round or square, very flat) and a gross or 2 of Dixie cups. Report weight of each stone.
Step 2: on a very level base (check it), chalk an outline of the stones. Arrange 9 or 16 cups in even spacing. Place a stone flat on the cups.
Step 3: repeat to see how high a stack can be made before collapsing.
Step 4: Video tape as stack builds - ideally with 2 cameras, one showing overall scene and one showing bottom 3 layers.
Step 5: Post video to UTube
Question: Does the tower tip significanly to one side or fall basically straight down?
Build another tower, but stop a layer or two before it collapses. Use a rod to punch out cups 25% of the way down from the top until the top starts to fall. Record falling pattern, does building fall straight down. This simulates fall of Buildings 1 & 2 of World Trade center. (Optional: place a bit of flour on each layer and paper sides to show blow out.)

A "Home Diagnosis Machine" that looks like a mini MRI machine in your home that you will use daily. First the machine takes a drop of your blood and saliva as a sample. Then you lay on the machine as it brings into the tube, just like an MRI machine. It scans you body for about 5 minutes, taking 3D images of your body and examining the blood. It would be able to tell you everything from your blood pressure, to cancerous tumors, to what vitamins you lack. Your results will be dispalyed on a touch screen. Everything that needs your attention will be shown to you. It will diagnose you and display what medication, vitamins, or medical attention you need. You select the medication you need to buy and the machine will send it to your local pharmacy.
