Why is the moon so low -- especially in the fall?
Have you ever noticed that, at certain times of the year, the moon seems peculiarly low in the sky? In this video, I explain the science behind that -- and I've tossed in a little Astronomy 101 lesson along the way. :)

The May 10, 1994 annular ("ring of fire") solar eclipse, as seen from Toronto. (I finally got my old VHS-C tapes digitized, and did a bit of editing. Anyway, a real blast from the past.) Enjoy!
Frans de Waal: Do nonhuman primates have a sense of justice?
Просмотров 637 месяцев назад
I had the privilege of interviewing primatologist Frans de Waal at length in 2012 at the Emory National Primate Research Center near Atlanta. (At that time I was working on a CBC "Ideas" documentary series called The Science of Morality.) In this clip, de Waal discusses conceptions of fairness and justice that some primate species (such as capuchin monkeys) appear to have.

Owen Gingerich on how Galileo changed science
Просмотров 93Год назад
We remember Galileo Galilei for his many discoveries in astronomy and physics but more than that, he changed how we think of science itself. Excerpt from a 2009 interview with Harvard astronomer and historian of science Owen Gingerich, by Dan Falk. Sadly Dr. Gingerich passed away in May 2023.
Owen Gingerich on Galileo -- and a brunch that changed history, in 1613!

Galileo had turned his telescope skyward in 1610. His shocking discoveries were still making waves three years later, when one of his former students, Benedetto Castelli, sat down with Christina, the Grand Duchess of Tuscany... (Harvard astronomer and historian of science Owen Gingerich, interviewed by Dan Falk in 2009.)

In the Footsteps of Copernicus
Просмотров 1783 года назад
Copernicus (1473-1543) revolutionized our view of the universe and of our own place within it. In this video we look at his life and times, and his science and we visit Warsaw, Torun, Krakow, and Frombork as we follow in Copernicus's footsteps in today's Poland. Video by Dan Falk (from a visit to Poland in 2018).

Galileo's "falling bodies" experiment re-created at Pisa
One of the weirdest unexpected things is traveling to the southern hemisphere and realizing the Moon appears to be upside down. Really, traveling between the northern and southern hemispheres, since the Moon up north would also be upside down for southies. Living on a tilted globe gives us some trippy features.
The moon is lowest in summer. Remember, the moon follows the ecliptic, which is lowest in summer, because that's where the sun is in winter.
But that would be a full moon, and as I say in the video, we're less likely to think of a full moon as being "unusually low" because we tend to notice it when it's just coming up above the horizon -- when (of course) it has to be low. In contrast to the first quarter moon, which is prominently visible in the south as the sun sets.
Very effective presentation of the basic relationship.
Thank you, Allan!
Can’t help but lol at the Beckers!
Yeah that seems fun. I can't remember what I was doing exactly that day, I was probably in school (high school). I vaguely remember the safety tips around it. I think it may have been too cloudy to see clearly that day out here in Oakville. Watching the 2024 eclipse was fun, the way the sky and heat etc. change as totality approaches is surprising.
curtis was right
I'm here today on the 8th of April 2024, just witnessed the Eclipse through NASA's live feeds... amazing to note that you did a video about this 1 year ago!
Great explanation of the eclipse on timing and when and were ,great job!👍🌓
I was in Guadalajara Mexico on this date. I remember when totality hit it got so dark roosters started to crow thinking it was daybreak again lol
My mom said the same thing lol. She was in Guanajuato Mexico. Everyone went inside because they thought it would affect them. They lived in a really small rancho so people did not know what it was.
Eclipse is today!!!!!!!
Very comprehensive!
Today is it
Imagine that. A Wonderous and Great God, Who created a Universe So unexplainable, He put it in Clear and Plain sight. Psalm 19:1..The heavens declare the glory of God, and the sky above proclaims his handiwork.
LUCKY I JUST SAW IN BING THAT WE CAN USE OUR CELLS TO VIEW THI WITHOUT HARM. NOT SURE HOW BUT PERHAPS MODERN CELLS HAVE A DARK MODE??!!
Stellarium has the moon and sun in Pisces! Why?
Pisces because it's April. When there's an eclipse, both moon and sun are at the same place against the stellar background.
Thank you. Great video 👍
What about Manitoba
My mother told me that in the 1960's she saw an eclipse that turned daylight into darkness just like at night! she told me that. and i was not even born!
when its comes to eclipses of the Sun - its all or nothing
I live in Montreal but driving to Sutton, QC to get an extra 2 min and 10 sec of totality. Question, for those who have never seen one...is it worth the hype...even if you've seen it in photographs?
All of this crazyness for 3 minutes.
That's what my wife says! 😂
I saw the eclipse from the north bank of the lago de Cuitzeo. My two friends and I were the only people there and there were no clouds nearby. Lake effect. The white rental car was covered with sleeping bees, flies, and dragonflies.
Thank you this was really helpful for my kids and I. Aiming to leave from Toronto for Hamilton some time around 15:00 ;-)
from Jeff: thanks for the video but the audio is way too sharp and hard on the ears I had to turn down the highs alot.
The weather forecast anticipates cloudy skies so will likely be a bust of an eclipse show except for the dimming of sunlight
Thank you for these details.
WHY??? did you not post proper times for TORONTO???? WTH??
they don't have a total eclipse, only 99.92%, the closest partial will be around 3:19 pm
I live in Brampton and my parents live in Mississauga, so I’m gonna pick them up and drive down to Niagara on the lake area. Initially, I plan to go on my own Fort Erie, but they’ve been advertising about it and I’ve heard it’s going to be a, you know what type of show down there. Crystal Beach look like a good location which is just outside Fort Erie on the Bank of Lake Erie, but I’m concerned about not getting down there in time. Then I got a email from a vineyard that we are wine club members of for an invitation, so I’m gonna go there and at least I can take my parents and there’s facilities for them to use as needed. Really upset. The weather isn’t looking to be forecasted for the greatest that late afternoon. 😢
Remember last statement : Hope it will be sunny day without any clouds or some snow.
What is fascinating about this solar eclipse is the interaction of comet 12P-Pons-Brooks and the timing of the eclipse in connection with the sign of the Son of man that Jesus prophesied would appear before His coming.
Guys do not get too excited because things are taking a dark turn. The solar eclipse looks like the ring of fire and the ring of fire represents a bad occurrence. Bad spirits are gonna came on April 8th and lock your doors stay inside and put oil around your windows. This is not fake. This is real news.
Thanks so much
"NOTHING god i am" my son , behold ! i am here to protect you !
Isn't it a Nova? Not "Supernova?
Being from Toronto and nit willing to drive that day this is a little upsetting lol
Thx for this! Just wondering, in toronto because its 99.9 is that still unsafe to take the eclipse glasses off during totality?
No, because you’re not in totality, so you don’t actually experience totality
It's been expressed that there will be devastation. I hope not. This experience is suppose to be a beautiful experience. I hope so. Just prep, just in case. I'm staying home. STAY HOME!!
You are aware there have been total eclipses in the past when the sun and the moon are both visible in the sky, but not overlapping each other. Research please. We are looking for the truth, and not the same old lies we have heard all our lives. I don't think you want to be in Paducah, KY when this occurs.
I am going to Buffalo to meet Jesus for the rapture coming in April, probably there will loud sounds in the sky and shaking on earth.
ith all this viral content for April 8th, I’m concerned that all this will most likely end up being one big “nothing burger.” That’s what is most likely gonna happen.
HI from Toronto Will try to record it then set it to Pink Floyd's bootleg set of Dark Side of the Moon live in Toronto in 94
I’d love to see it!
@@ArtCoven hoping it's going to be clear and it turns out
Great video, thanks.
Thank you. Great information.
Oh my, i remember that one when I was a kid... Don't know the exact time or date, but I do remember the excitement, the dark welding glass i was trying to see through 😅 i don't know what I was expecting, but i do remember daylight dimming as if it got cloudy all of sudden. Looking forward to seeing it again
😂😂😂😂😂😂
It's not about seeing the eclipse .. it's what the eclipse is all about. April 8th begins the New Year from Yahuah's perfect calendar. The Pagans, aka "Christians" wholly reject Heavenly Father for JeZEUS who is the LORD of the SLAVE. No longer a son or daughter of Heavenly Father, Christians love the SLAVERY JeZEUS brings to them. Even tossing them to the lions did nothing to stop their pagan ways ... Judgment may be falling on the Patriots and Christians who have sold God's property by voting ... a contract, social contract which Heavenly Father warned us about!
I am concerned!! There is a black hole going around the earth. Which in turn is very dangerous. So the Eclipse is earth, sun, and moon. What happens if the moon or the sun touches the black hole at the time of the Eclipse. Are we all history on April 8th 2024. I don't know!! Just putting it out there!! Never know what can happen!! I hope I am wrong!!
It never gets as dark as we might hope largely because of the corona I suspect.
not true ,,,,,,, you can see stars - its jaw dropping
I live in Pittsburg New Hampshire, on the Canadian border. Hopefully it will be a nice day.
I like the description of traffic as a plugged drainpipe.
