Is There Anything You Can Tell Us To Expand On The Space Time Ripples Found In Simulated Black Hole Collisions?

The astro-fashion-loving Internet collectively gasped when ESA’s Hubble twitter account posted three gorgeous gowns, by Czech designer Jirina Tauchmanova with only credit “Photo: Vasek”, which google thinks is a Canadian tennis player. For four long days I couldn’t find anymore images, until, today! Which is why I’m sharing a belated #FashionFriday and #StarrySunday combo.

These gown were shown at Serbia Fashion Week back in December 2015 as Jirina Tauchmanova‘s Spring/Summer 2016 collection – I hope that means they will be available for purchase soon!

I think I recognize at least two of the images, NGC 602 & 30 Doradus, but I’m going to have to see these in person to be sure, yes, definitely, and probably try them on, too.

There’s a rare type of blood that’s shared by only 43 people in the entire world.

‘Rhnull’ blood doesn’t contain any of the Rh antigens that 99.9% of humans have. It’s often called ‘golden blood’ because it can be given to anyone who has a rare Rh blood type, but there are only 9 active donors, so it’s only used in extreme circumstances.

The maximum life span is a theoretical number whose exact value cannot be determined from existing knowledge about an organism; it is often given as a rough estimate based on the longest lived organism of its species known to date. A more meaningful measure is the average life span; this is a statistical concept that is derived by the analysis of mortality data for populations of each species. A related term is the expectation of life. Life expectancy represents the average number of years that a group of persons, all born at the same time, might be expected to live, and it is based on the changing death rate over many past years.

The concept of life span implies that there is an individual whose existence has a definite beginning and end. What constitutes the individual in most cases presents no problem: among organisms that reproduce sexually the individual is a certain amount of living substance capable of maintaining itself alive and endowed with hereditary features that are in some measure unique. In some organisms, however, extensive and apparently indefinite growth takes place and reproduction may occur by division of a single parent organism, as in many protists, including bacteria, algae, and protozoans. In order to consider life span in such organisms, the individual must be defined arbitrarily since the organisms are continually dividing. In a strict sense, the life spans in such instances are not comparable to those forms that are sexually produced.

There is a brief period during which it is impossible to say whether an organism is still alive, but this time is so short relative to the total length of life that it creates no great problem in determining life span.

Some organisms seem to be potentially immortal. Unless an accident puts an end to life, they appear to be fully capable of surviving indefinitely. This faculty has been attributed to certain fishes and reptiles, which appear to be capable of unlimited growth. Without examining the various causes of death in detail, a distinction can be made between death as a result of internal changes (i.e., aging) and death as a result of some purely external factor, such as an accident. It is notable that the absence of aging processes is correlated with the absence of individuality. In other words, organisms in which the individual is difficult to define, as in colonial forms, appear not to age.

Five women shaking up the science world

From pushing boundaries to defying stereotypes - five women who are breaking barriers in science.

The gender divide in science is cultural rather than anything to do with women’s brains and some countries do much better than others, she says.

In astrophysics southern European countries like France, Spain and Italy do much better than northern European countries like Germany and The Netherlands, for instance.

“In all those countries the proportion of women is going up but the pattern has stayed the same, which is interesting,” she says.

“The progress is slow, things are changing gradually.”

Her advice to women in science? “Don’t be daunted, hang in there, work hard, of course, be courageous.”

Got these notebooks for 5 cents so obviously going to buy more than one :D # strongnotebookgameisstrong

There’s a method to my madness I swear!! OK so on avg I seem to use up two of those 80 pg notebooks so I got two for each class. And consequently I needed the 4pack 32pg exercise books. 

The 80 page notebook is used for in class notes. As soon as anything important is said it is scribbled down into the notebook.  The 4 pack 32 pg exercise book is divided to two groups: Feymann technique and Cornell method.

Feymann Technique

Right after class I grab my textbook, my notebooks and two of  my exercise books. I teach myself the lesson primarily with my notes and if I don’t understand something I turn to my textbook. If I am still lost I leave space and note that there is something I need to clarify with my professor. Even while I am doing this, I force myself to decrease the writing and increase the connections between every topic since the 32 pg is quite smaller than the 80 pg. 

Thankfully when I am done with this, my 32pg becomes the go to whenever it seems like I am in need of revising a topic since it contains relevant notes from both my textbook and my notebook in my own words. 

Cornell Method.

When exam time approaches I convert my notes into the cornell notes so that I can easily test myself with the main ideas and key questions.

There is no better way to revise than to try to make connections. That is all you are going to get tested on since it’s not that hard to spit back words on a page. Instead of being asked about photosynthesis for example, you might be told about some chemical that is sprayed on a plant that will block one process and asked about how that affects the growth of the plant overall. See what I mean? 

I usually get a whiteboard and write all of the connections out and in front of me. When THAT  is done I write it down in flashcard mode and quiz myself for the next week using the Leitner system, along with the topics that are basically just memorization.

LEITNER SYSTEM

Label 5 boxes 1-4, where 1 is for cards you don’t know and 4 is for cards you are basically a pro in. You frequently test yourself in box 1 (maybe every 30 mins, you choose) and increase the time in which you test yourself until you reach 4, where you would test yourself just once a day. 

In the beginning all of your cards go in box 1,and as you get a card right it goes up a level and if you get it wrong it goes down a level. That way you are spending more time with ideas and topics you don’t have a strong hold on, rather than spending equal time with all the topics. 

At this point I have rewritten my notes twice in my own words and then converted them into flashcard mode :) I recommend this method when it comes to the sciences or humanities. For the maths I have already done a post about it here. 

Hope this helps for those still looking for study techniques!

These slides, presented during the New Horizons’ press conference at the 47th Lunar and Planetary Science Conference, show the climate zones of Pluto compared to Earth. Pluto has an axial tilt of 120°, which creates extreme tropic and arctic regions. The two regions overlap, creating a ‘tropical arctic’ region that experiences both direct sunlight and prolonged sunlight and darkness. At the moment, Pluto is in an intermediate state between the extreme tropic and arctic climates.
