Lights of Human Activity Shine in NASA's Image of Earth at Night

NASA scientists have just released the first new global map of Earth at night since 2012. This nighttime look at our home planet, dubbed the Black Marble, provides researchers with a unique perspective of human activities around the globe. By studying Earth at night, researchers can investigate how cities expand, monitor light intensity to estimate energy use and economic activity, and aid in disaster response.

It's a Matter of Perspective

"There's a flip side to everything," the saying goes, and in 2 minutes, Derek Sivers shows this is true in a few ways you might not expect.

Via Seth Dixon
Seth Dixon's curator insight, September 7, 2016 8:12 PM
In this ultra-short TED talk, Derek Sivers show that what is considered true is often dependent on your perspective, the context, and how it is situated within a particular paradigm.  This is a mind-blowing video because it exposed our framework (which might go unquestioned as universal) to be but one of many ways in which to organize the world and the information within it.  His first example is the Japanese address system (I prefer to show this version of the same material since the visuals are better).  I also enjoy showing this clip together to hammer home the point that our perspective shapes our view of reality.

Why Mercator for the Web? Isn’t the Mercator bad?

Why Mercator for the Web? Isn’t the Mercator bad? | HMHS History |

"As you may know, Google Maps uses the Mercator projection. So do other Web mapping services, such as Bing Maps and MapQuest. Over the years I’ve encountered antipathy toward the use of the Web Mercator from map projection people. I know of two distinct schools of opposition. One school, consisting of cartographic folks and map aficionados, thinks the Mercator projection is 'bad': The projection misrepresents relative sizes across the globe and cannot even show the poles, they are so inflated. The other school, consisting of geodesy folks, thinks mapping services have corrupted the Mercator projection, whether by using the wrong formulæ for it or by using the wrong coordinate system for it."

In this article you will find a thoughtful discussion of the reasons why the Mercator projection is disliked by many, but still so prevalent.  In ArcGIS online, you can Search For Groups and then enter Projected Basemaps to see many map projections on that platform.

The Daily Show–Spot the Africa

Between rampant racial inequality and Ebola outbreaks, South African comedian Trevor Noah admits he hesitated to visit a country as underdeveloped as America.

Re-scooped from Professor Dixon. This correspondent is actually from South Africa and he's pretty damn funny. I remember how freaked out my ex-girlfriend was that she was going to get Ebola. And the reference to saving African's for just five cents a day made me giggle. Also, it's pretty funny how bad the FDR looks.

There is no doubt that there a stereotype and a generalization people make to Africans. This clip really emphasize those points and turn it into comedy, which is very creative. It makes people like me laugh at ourselves sometimes at the things we do as far as branding a group of race base on popular culture.

As comical as this is, it goes to show the kind of racism and pride we have in our country. Here the guest speaker says he took multiple photos of different places and wanted the host to figure out if it is America or Africa. Most of the photos showed undeveloped or terrible sections of the US and opposite for Africa. Each time the pictures were shown, the host assumed it was Developed America and underdeveloped Africa.

Kevin Nguyen's curator insight, November 24, 2015 11:52 AM

I cannot believed the size of Brazil is at this scale because we don't hear a lot about it as being a world power. It shows that even though the country is this big, most of the land is uninhabitable due to the forests and geography of the land. In addition, from history class one cannot imagine a small country like Portugal controlled a big country as Brazil from the colonial times. Seeing this map with all these European countries inside of it with some space leftover, one can see the massive size of this South American country.

Adam Deneault's curator insight, December 7, 2015 12:47 PM
This link to show me a picture of Europe fitting in Brazil is astounding! I never realized how large this country was until it was put together like a puzzle for me. For a single country to be that large that you would be able to fit an entire continent inside is absurd. That really goes to show that looks can be deceiving.

By looking at these images it is apparent that heir is a clear distincition between how one may view the monument from upclose andd then when you take asep back you can really appreciate it by seeing others appreciate it as well. As an observer you can also identify the different persepectives by looking at it in a different light by either taking a step back or viewing it from a different vanage point. Knowing the history of the monument also helps with a background story in order for better appreciation of the monument and the History that goes along with it.

Unit 1 Geography: Its nature and perspectives

Although the article relating to this diagram is in Russian, the diagram is not, and I found it to be a very interesting visual to not only show world religions developing on a time scale, but also because it does a very good job of showing just how many little divisions of each religion they are, and how they are all intertwined. Zooming in on the diagram, you are able to see each divide, each new branch, and each date for hundreds of sets of information.


This illustrates the theme of identification of major world religions because it simply shows the mass amounts of tiny divisions that occur in the major world religions in a simple format. This is very helpful because this would be pages of writing if you tried to write it all out.

Cultural Perspectives

Cultural Perspectives | HMHS History |

Shelby Porter's curator insight, November 4, 2013 10:12 AM

This political cartoon is just another great example of how different cultures are across the globe. Here in America, we are told that the appropriate swimwear to wear to the beach only covers about a third of our body. Where as in the Middle East, wearing a burka is what they are told is the right type of clothing to wear. Whether it be for religious, cultural, or fashionable reasons, women wear all types of clothing and I don't believe it is directly due to male influence. There are many things that could cause this influence such as the church, family, or the media. Yet as the cartoon says, each woman thinks the men in that country are forcing them into wearing clothes like that and their culture is dominated by men. I guess it just shows the different perspectives each culture can have. 

megan b clement's comment, December 16, 2013 12:51 AM
This cartoon depicts the cultural differences between two different cultures. On the right you have a woman in a traditional burka that covers all but her eyes. On the left you have a woman in a bikini which is what is apropriate to wear on the beach or to bed. Two totally different societies and beliefs and they both look at one another and see the other person as inapropriate. This is not the first time another country has looked at the USA and turned their nose up to something that we do differently.
Jacqueline Landry's curator insight, December 16, 2013 6:31 PM

when I look at this the first thought that comes to mind is it is easy for other people to judge. just by there comments they have no idea what the others beliefs are,. This is a classic judging a book by it's cover. The are both assuming it has to do with a male dominating world. I think it has to do with what you are comfortable with.

Seth Dixon's curator insight, March 28, 2:21 PM

Personally, I'm not a fan of this decision, but it's as if they watched the classic West Wing clip and decided to roll with it. I think that the Peters projection map is better than the Mercator for most educational applications, but it isn't the "right, best, or true" map projection.  Many viral videos comparing the two love to exaggerate and say things like "The maps you use are lying to you" or "the world is nothing like you've ever seen."  Yes, Mercator maps distorts relative size, but it isn't a "wrong" map anymore than the Peters projection.  All maps have distortion and map readers need to under that all maps are a mathematical representation of the Earth.

Geography as a Primary Source

Geography as a Primary Source | HMHS History |

"A geographic perspective is a way of looking at and understanding our world. When you view the world through the lens of geography, you are asking who, what, where, when, and how people, places, and things are distributed across the surface of the earth, and why/how they got there. In other words, it means that you are analyzing something with a geographic perspective. The understanding and use of a geographic perspective is critical for decision making skills in the 21st century. Using spatial concepts such as location, region, movement, and scale to help us understand:

Interactions - How the world worksInterconnections - How systems in our world are connected Implications - How to make well-reasoned decisions"

Our preconceived notions of places, as well as some of the dominant narratives about regions, can cloud our understanding about the world today.  This video is a good introduction to the Ignorance Project which shows how personal bias, outdated world views and news bias collectively make combating global ignorance difficult.   However, the end of the video shows some good rules of thumb to have a more fact-based world view.

Avis aux parents irresponsables qui refusent la vaccination!!! Seth Dixon's insight:

<< I had measles back in 1977, when I was too young to be vaccinated during an outbreak in the Southern California region.  My father-in-law still lives with the effects of Polio that he contracted when he was a toddler, right around the time of Jonas Salk's great discovery that lead to the Polio vaccine.  I care about this issue because the effects are personal--but for too many, they've never known the realities of a world before vaccines. We collectively have forgotten WHY life expectancy and have steadily gone up over the decades at the same time that infant mortality rates have dropped.  It's in large part because the nightmarish diseases of yesteryear have been eliminated, if we collectively are all immunized. Unfortunately, this is the discouraging truth (for now): anti-vaxxers are nearly impossible to convince. I hope this current measles outbreak is the tipping point for their to be enough public sentiment to lead to change. >>

Is your state on here?

Caitlyn Christiansen's curator insight, February 24, 2015 7:41 PM

"Shots Before School. It's the Rule." This slogan is posted on our school website and many other places, but there are exemptions from the rule. 19 states will allow exemptions for philosophical or religious reasons. 48 states and Washington D.C. will allow only religious exemptions. Only 2 states will not allow any exemptions at all.

America is founded on principles of religious freedom and the ability to choose for yourself. It makes sense that the majority of states would allow some sort of exemption for religion. What is really interesting is that the only 2 states with a no exemption policy are Mississippi and West Virginia. The states that allow philosophical exemptions are usually clustered in groups and spread their beliefs and rules to one another. Example: The Bible Belt

Via Seth Dixon
Kristin Mandsager San Bento's curator insight, April 9, 2015 2:21 PM

Before I even read the article, my first thought went to the Linneaus classification.  That really damaged history with this one chart.  I think people still think of Africans and blacks(very dark blacks) as dirty or unintelligent.  Which is horrible and couldn't be further from the truth.  Misinforming the public is criminal.  News media and social media need to be careful and educate properly.  I've been asked from a customs offical, "Have you been to Africa in the past 6 months?"  Which is a very blanket question because Africa is a continent.  There were areas that were not hit with Ebola.  

Chris Costa's curator insight, October 27, 2015 4:37 PM

Those who deny the continued influence of racism in our society are blinding themselves to the truth. Contemporary influences of the racism that plagued the preceding centuries are still found in most major media depictions of Africa. The Ebola epidemic has served to highlight the bigotry that plagues Western media, as the assumption that all of Africa is diseased and dirty is continuously perpetuated (when, in reality, Ebola only affected a very small part of the continent). Africa is presented as "other," a backwards continent that is in desperate need of Western help and guidance- in what was is that different from the European colonizers who also viewed their actions as benevolent attempts to "civilize" the uncivilized? That mindset has not left Western circles, and yet we continue to pat ourselves on the back and congratulate ourselves for suddenly being so tolerant. The insensitivity of Western audiences to the concerns of black individuals both at home and in Africa related to the prevalence of racism highlights how determined mainstream media is to deny the existence of a problem. Until we recognize the Eurocentrism that continues to plague our media and make the necessary moves to correct the practice, harmful depictions of Africa will continue to loom large in Western media and in the opinions of many Europeans and Americans alike.

Mark Hathaway's curator insight, October 30, 2015 7:12 AM

Africa has long been treated by the western media as a dark , brutish, uncivilized place. Africa is a place were people starve and murder each other in large numbers. There is so much more to Africa than the picture I just described. The problem is, many people just do not accept the existence of a culturally complex Africa. That narrative would destroy the traditional  darker narrative of the past 500 years. A narrative grounded in the beliefs that blacks are inherently inferior beings. During the Ebola crises, the calls to cut off travel to Africa were quick and demanding. Had the crises been in England, would those same calls have been so loud? I think we all can guess the answer  to that question. Much progress has been made, but we still need to change our cultural depiction of Africa.

Earth's Cosmic Context

"Superclusters – regions of space that are densely packed with galaxies – are the biggest structures in the Universe. But scientists have struggled to define exactly where one supercluster ends and another begins. Now, a team based in Hawaii has come up with a new technique that maps the Universe according to the flow of galaxies across space. Redrawing the boundaries of the cosmic map, they redefine our home supercluster and name it Laniakea, which means ‘immeasurable heaven’ in Hawaiian.  Read the research paper here."

Spatial thinking and geographic exploration is constantly seeking to understand place in context to other places.  More often than not, that is done without every venturing beyond this planet, but in many respects, space is the greatest of contexts on the grandest of scales for us to understand ourselves.  I first saw this video embedded in an NPR article and it filled me with wonder to think about the immensities of space and that the Earth is such a small little corner of the universe.
