Is Pluto a Planet Again?
Short answer: No.
I have seen far too many posts lately about Pluto being reinstated as a planet by Harvard astronomers - but that’s quite far from the truth.
What actually happened was a debate, and at the end of the debate the audience (Which was open to the public!!!) was asked to vote on whether it should be a planet or not.
And the funny thing is - that wasn’t even what the debate was about. It was about whether or not dwarf planets should be considered a subsection of planets, instead of an entirely separate (though related) section of celestial objects. (Like asteroids and comets.)
Now i disagree with this, for the simple fact that if pluto were a planet, it would mean so are the other 5000-odd objects that are JUST LIKE pluto itself. we would go from having 8 to having 5000+, not 9.
But what do you think?
gojira--gojira asked: I think with math, it is complex, yet can be satisfying to understand, but it also depends on who is teaching the subject. There are teachers who will teach math in a way that's boring and stressful, no added fun into finding the answer and all. I've hated math, just because I've had so many teachers that were snobby and made me uninterested in math, based on their attitude and teaching style.
Thank you, that was something i forgot to mention.
I also think teaching style has a big role in it. I had 1 teacher in year 11 (15 year olds) who was just ecstatic about math, he loved it, and it showed in his teaching style. I was already interested in mathematics by the time i had him as a teacher, so i guess that played a big role in my education.
But if you have a bad teacher, i really hope you blame the teacher and not the subject. incompetent teachers play an enormous role in the failure of education systems.
Luckily at the university level all lecturers are enthusiastic about what they’re teaching, and its wonderful to see them teach it.
Anonymous asked: A lot of people just don't have the type of brain to ever understand it! Do you think writing essays and poetry is fun?
I always hated this explanation.
I completely disagree with the whole two sides of a brain argument - where a person is either more interested in art and music and literature, OR science and mathematics.
I do actually enjoy poetry, anon. And depending on the subject - i also enjoy writing essays. I love history, and politics, and creative writing (i even tried writing fanfic, though my grammar was horrible at the time.)
I think it just comes down to a lack of understanding, people see numbers and think ‘ew’ and so they don’t even try to understand what they mean, and so many people complain when they’re first taught algebra - “letters have no place in math.” Well i haven’t seen any number in mathematics in years, its all just letters. Real mathematics is a general solution, and general solutions have no numbers.
The most common answer im getting is “It’s the way its taught. incorrect answers are punished, etc.”

Which I think is quite comical, literally every school subject is taught like that, except maybe art. Get the wrong date in a history essay? you get penalized. Spell a word wrong in english? Penalized. Say the wrong meaning of a word in spanish? Penalized.
And yet still math is hated more than any of those subjects.
I was also getting a lot of learning dissibilites as a problem, which i accept as a problem for some people (dyscalculia is like dyslexia with numbers.)
I think a big problem is people hear all the time that math is hard, that its boring and that its confusing, so kids going into middle school or high school seeing new problems in mathematics and having a few difficulties understanding them give up far too quickly. No one understands math right away, unless you’re one of those very few 1-in-a-million math geniuses that get doctorates at the age of 17. Everyone struggles at first, but if you try and try and try you will understand it, and trust me when i say this - it is fun!
I remember this one time in year 13 (last year of high school) i was with a few friends and they were all studying for a math test, I had found this one question earlier that seemed close to impossible, no one could do - so i sat there while my friends were all studying, trying to do this one problem and it took literally 4 hours straight - but i did it. and it was an amazing feeling finally finishing it, it was like doing a jigsaw puzzle but having 1 missing piece and finding it after hours of searching.
And since then I always use the analogy - Math is like a puzzle, and should be approached with the same attitude as every other puzzle - like its a fun challenge.
Why do people actually hate mathematics??
This isnt one of those posts explaining a question posed in the title… i’m actually curious - I Love mathematics.
I dont understand how people don’t like it, even when i find a concept hard to understand (which has been a lot, lately) I still enjoy it and want to figure it out. I have always loved it, all the way up through high school and now i’m majoring in it (and physics) at university. I honestly don’t understand why it gets so much hate, It’s Fun!!
Anonymous asked: How would you compare what Rocket Lab is doing to what SpaceX is doing?
I think it comes down to different missions, SpaceX is in it to eventually put people on other planets, which is a long way off atm. RocketLab want to provide a economically viable platform for companies to launch satellites into orbit.
SpaceX has an average mission cost of about $100 million, something only Governments and high end companies can afford while Rocketlab’s electron rocket costs only $4.9 million to put a satellite into orbit.
Of course SpaceX does have the job of resupplying the ISS as well as other, more tasking missions, but regardless of that, a space program costing that much per mission is not sustainable. It Needs to be cheaper, which Rocketlab have accomplished with their light weight design, and efficient engine.
