Fig. 4 Selection of intermediate feature maps in the first (top row) and second (bottom row) layer of the neural network.

‘One of the strengths of CNN is that the feature map at each layer is an image that can be visualized. We report in Figure 4 a selection of features maps from the output of the first and second layers. We can see that the first layer contains some low pass or directional filtering whereas layer two contains more semantic information.

I’m so angry about the Humanity Star. Who the ever-loving hell thought you his was a good idea?? This is literally the worst thing since literal wasps

I KNOW! Like, I’m totally down with their goal of “inspiring people to look up,” but the space station exists?!?! You could accomplish the same thing by putting out ads that are like “YOOO there are people in space right now and you can SEE THEM and also earth has not had all humans on it at once since 2000!!!” 

Apparently the rocket that launched it is this awesome new rocket design for micro-sats and it uses batteries as part of the rocket, so I’m totally down with that too, it’s just they didn’t even think about the impact of their publicity-mission on actual astronomers.

Tens of thousands of meteor’s an hour lit up the skies and many people thought the end of the world was at hand.  This meteor storm (a magnificently prolific showing of the Leonind Meteor Shower) was the beginning of our understanding of how comets and meteors work.  Follow the link for the whole story and a fantastic interactive map of earth moving through the comet’s tail.

A total solar eclipse occurs when the moon, moving between the sun and the earth, completely blocks the light of the sun. An optimal view of this type of event can be found within the path of totality – the area where the umbral, or darkest portion, of the moon’s shadow falls upon the earth's surface. The path of totality is typically thousands of miles long but often less than one hundred miles wide.

When a total solar eclipse was anticipated in the mid to late nineteenth century, astronomers began travelling to areas within the path of totality to take pictures and record their observations. Staff members of the University of Chicago’s Yerkes Observatory were among those early adapters of astronomical photographic technology. From the year 1900 onward, these scientists left their observatory in Williams Bay, Wisconsin, and journeyed to distant regions in order to document the moments in the brief life of an eclipse.

Solar eclipse images, including close-ups of prominences, coronas, and Baily's Beads, taken by Yerkes staff are available in the University of Chicago Photographic Archive as are snapshots of life on eclipse expeditions.

I love the stars. Because they can’t say anything. I love the stars. Because they do not judge anyone.

Oamenii care se află în spațiul cosmic sunt numiți astronauți, ceea ce înseamnă "marinari ai stelelor". Acesta însă nu este un termen utilizat de toată lumea. Spre exemplu, în Rusia, oamenii care se află în spațiul cosmic se numesc cosmonauți, ceea ce înseamnă "marinari ai universului". Primul om care a zburat în spațiul cosmic a fost pilotul militar de origine rusă Yuri Gagarin. #arta #cultura #romania #moldova #enciclopedie #educatie #descopera #istorie #interesant #followme #cunostinte #astronaut #yurigagarin #gagarin #astrononmie #spatiucosmic https://www.instagram.com/p/B2d9iBqgwI_/?igshid=tgtodeqlzek3

Just wanna say YOU ARE SO STRONG GIRL! KEEP GOING WITH YOUR STUDIES🔥I would've died with all those exams and essays😭 Any advice on how to study well?👀

AWWWEE THANKS BABE 😭😭💜💜💜

Honestly, by no means am I an expert, and some of my tips may or may not work for you. But, if I were to give suggestions, it would be these 5:

Tip #1: study what you love.

I know this isn’t always an option depending on your circumstance. I spent approx. 6 years of my life, working/studying education thinking I was going to be a resource teacher. Once I graduated, I was so unhappy and realized that I never wanted to do that. I just did it because it’s what people expected me to be, and since I was good at it - why not do it? Philosophy is a lot of work. A lot of writing & critical thinking. Sometimes, I come home and rage - but fuck, do I love it. And it’s that passion that motivates me, something I didn’t have when I was studying education. Kind of with my story writing. It’s a lot of work, and realistically, I don’t get paid to do it (although some of you donate to my ko-fi account and I can’t give you enough hugs and kisses for that) but I love it so much, and it brings me so much joy that I'll use my free day in the week to write. Finding something that gives you drive makes studying ten times easier. 

Tip #2: going to class.

Trust me. Waking up for those morning classes KILLS ME. But I learned that if I just go to class, and listen (and I’m talking about being the goodie-two-shoes and sitting front row and center), the amount of time I spend studying is cut by half. I remember the overall lesson, so studying is not so much studying but a refrsher. Also, in Canada, we have to pay for our schooling. I pay around $8000+ CAN per year (#brokestudentlife). So for me, I’m going to get my money’s worth 🤣

Tip #3: teaching/talking out loud.

This is my rule of thumb; if I can teach someone (who has no background knowledge of x major) a concept from that major and they fully understand it - you got it. My fiance thinks I’m nuts. He’ll come home to me talking to myself as if I was teaching someone. And sometimes, I’ll make him sit down, while I rant - and if he gets whatever I’m trying to study, then I know I got it. I managed to teach my mother logic 😅. This woman is retired and couldn’t care less about arguments and true or false statements, but she can proudly say she knows how to construct a truth table 🤣 Point is - for me, talking out loud/teaching is a way for me to gauge what I do know, and what I still need to learn or improve.

Tip #4: breaking the concept to its purest form.

I had an exam, and I was the only one in the class who answered the question with four sentences, everyone else answered it with 2+ pages. I was the only one who got 100 for that question. Sometimes, less is more. I simplify a theory to its core. Once I completely understand the basics, then do I start adding to that theory. It’s like building a house. You can’t start decorating a house that isn’t built - you first got to build it; same way with studying. This helped me a lot when I was studying Astrononmy. I have no knowledge or background in such a field. But after my mini-panic attack and questioning my decision for enrolling in such a class, I realized that if I just break things down, I can do it. And I did do it after a lot of tears and nail biting 🙈

Tips #5: thought-experiments/examples.

I had to take the ‘philosophy of the mind’ and I remember my prof. was trying to think of an example, and the girl beside me had this coffee cup. Since it was the first thing in front of him, he used that coffee cup as an example. Four months later, almost every example we had was somehow related back to that coffee cup. It was hilarious because we would get our exams, and every single person would use a coffee cup in their example because that is what we thought of everytime we thought of x theory. Attactching examples to a concept or having a thought experiment is a really good way to remember things. My friend assocates music with theories. It’s been 3 years since I’ve taken that philosophy course, but I can till this day tell you about the theory because of that damn coffee cup 🤣

Sorry, this kind of turned into a rant, but honestly - if this post can help just one person out - it’s totally worth it.

Everyone learns at different paces and styles. So don’t beat yourself up if it takes you a whole week to study something while someone else can study in a day. Everyone has their strengths and weakness, and as much as we wish, we can’t be perfect at everything. But I think as long as you try, it shows.

Best of luck with your studies, hun, and hopefully this helps you out~💜💜
