Is it a bar? Or a histogram?

Muscle strain much better. And I got good assignment scores - 89% for the tutor marked one and 100% for the computer marked algebra/arithmetic. So maybe I am back in the groove. But I am struggling with the difference between a bar chart and a histogram. Everything I read makes me more confused than ever.

The volcano and earthquake section of the course was very interesting - especially since it concentrated on an area at the north end of the Pacific Ocean, where I will be cruising later in the year. Over all that frenetic earth activity.

Next section is chemistry again.

Sitting quietly at home

I have managed to pull a muscle somewhere near my hip. It has been very painful all day and I have done very little to advance my degree in astrophysics. I am actually feeling like an old lady, which is very rare for me. I have been sometimes sitting and sometimes trying to move around. I have not done any of it quietly. Fortunately it was not my turn to make dinner.

Getting there

The second assignment went better and I have reasonable hopes for the third and fourth. My main concern now is that I am so slow. Maths techniques I used to live and breathe now have to be grappled with. No idea if I am improving but I feel a bit sharper in my mind so maybe I am achieving something.

First marked assignment

78%. I am pleased with this, but dismayed that all the people on FB who are saying what they got have (apparently) scored well over 80% and in one case 99%. So I am bottom of the class. But what about all the people who haven't said?

I lost most of the marks on reading and describing the cell specimens I could see through the virtual microscope. I found this part of the course fairly incomprehensible, not to say uninteresting. I hope I never have to do anything like that again. If it turns out that I do have to, I might have to do some extra study. On something that bores me to tears?

Improvement

I did my first ever on-line computer marked assessment. Only 5 questions on fairly basic maths. I have a good O level (GCSE) and a good A level and an honours degree in maths. But it was so long ago that I was petrified about getting them wrong. And under pressure not to disgrace the bright young person I used to be. But I got them all right first time. It felt like a huge achievement even though that bright young person would be scathing about how long it took. Pathetic!!

Me doing biology!!!!

I have been reading about cell types and organisms. This is not really my thing and I hope that I can do just enough to get through - I have no intention of doing any more biology if I can avoid it. It seems like a massive memory test to me. If you go to IRL lectures, you would hear the words over and over again and they might go in, but it is very difficult just reading and writing about them. 

 I tried the virtual microscope practical this afternoon (they have a page set up so that you can replicate most of the functions of a real microscope) and they said to allow about an hour. But they are asking for measurements on 45 slides. Even at 5 mins per slide (and my first few took a lot longer than that), it would take around 3 and a half hours!! Have I read it wrong?

And another experiment not doing it

This time I had to put water into a plastic container, weigh it and mark the height of the water and freeze it overnight. The next morning the water was frozen and still weighed the same (good). But the ice still seemed level with the mark I had made ie it had not expanded as it should have (bad).

The rest of the course is interesting and not, on the whole, difficult. I either never knew, or had forgotten, that there is a 'triple point' where water can exist simultaneously as ice, liquid and gas (steam).
