What keeps you up at night?

Continued from: Everything is made out of this. Everything

The things with which we concern ourselves in science appear in (many) forms, and with a multitude of attributes. For example, if we stand on the shore and look at the sea, we see the water, the waves breaking, the foam, the sloshing motion of the water, the sound, the air, the winds and the clouds, the sun and the blue sky, and light; there is sand and there are rocks of various hardness and permanence, color and texture. There are animals and seaweed, hunger and disease, and the observer on the beach; there may be even happiness and thought. Any other spot in nature has a similar variety of things and influences. It is always as complicated as that, no matter where it is. Curiosity demands that we ask questions, that we try to put things together and try to understand this multitude of aspects as perhaps resulting from the action of a relatively small number of elemental things and forces acting in an infinite variety of combinations.

For example: Is the sand other than the rocks? That is, is the sand perhaps nothing but a great number of very tiny stones? Is the moon a great rock? If we understood rocks, would we also understand the sand and the moon? Is the wind a sloshing of the air analogous to the sloshing motion of the water in the sea? What common features do different movements have? What is common to different kinds of sound? How many different colors are there? And so on. In this way we try gradually to analyze all things, to put together things which at first sight look different, with the hope that we may be able to reduce the number of different things and thereby understand them better.A few hundred years ago, a method was devised to find partial answers to such questions. Observation, reason, and experiment make up what we call the scientific method.

Everyone Has A Story - This is Ours

WHO WE ARE We are EduAfrique a not-for-profit group committed to creating an equitable world in which everyone has access to basic human needs. We contribute to bringing clean water, sanitation and hygiene (WASH) programs to communities in Ghana, Africa. We believe access to WASH infrastructure and services is a prerequisite for changing and lifting communities out of a cycle of disease and poverty.      WHAT WE DO Thanks to donations from people just like you, we partner with communities in Ghana to provide better access to WASH. In 2013 we conducted a 6-month health promotion program in Asamang, Ghana. Through this work, our eyes were opened to the social and economic consequences of lack of WASH in the realms of education and health. Following a set of fundraising events in 2016, we were able to partner with a community in the West of Ghana - called Bronikrom - in January 2017 to construct a composting toilet for the community. The population of Broni

Saying NO to Single-Use Plastic

Image credit: Ndudu by Fafa In the early hours of the day, when the compound has been swept, the face and body washed, and the pearly whites brushed, a long familiar urge can now be addressed. Breakfast. You walk down the street to the koko seller. Or perhaps for you, it's the Waakye seller. Or yet others, the Gari-and-beans serving is just what you crave. Then it starts:  You get your Koko/Waakye/Gari-and-beans. The seller places these items in a clear plastic bag. It's so convenient that you think nothing of it. You came to buy food with your younger brother or sister or friend, so you order some food for them as well. The food seller places these in a separate clear plastic bag. You remember that mother also requested some food, so you order a serving just for her. The food seller works so efficiently that it's almost mesmerising to watch. She places each of the clear plastic-bound food into it's own perfectly sized black plastic bag. Then with the intention of makin
