The science of the perfect piano sound

A grand piano has always been viewed as a symbol of class in anyone’s home. The sleek design and polished aesthetics add a look of luxury to any room and when played in the perfect space it can create a phenomenal sound that travels magnificently through your home. There is an unmatched sound that comes from a grand piano that no other type of piano can produce because of the size of the piano itself. Although digital pianos can simulate a sound close to that of an acoustic piano, the grand piano has a fuller sound that cannot be recreated on an instrument of a different size.

How to find a well-paid job with having a space science degree

Finding the right job for yourself is not the easiest thing to do, especially if you are just fresh out of college or haven’t worked for a while after a long break. Moreover, some people just go on to work in a different field than their college degree and then decide to return to the field they initially chose for their career.

Whatever your situation is, it’s important to remember that there is always a chance of finding a good position in your field – or at least starting out in a bad position and working towards a better one. Hence, here’s how to find a well-paid job having a space science degree.

The Effects of Soil Erosion on Our Environment

Soil covers all of the earth, and it’s more than just rocks and plant matter. These layers of soil are teeming with biodiversity and living organisms. Your food largely depends on the soil where it is grown. If there isn’t enough of one nutrient or the soil’s structure is failing, then the amount of food you have to choose from will decrease.

Natural ecosystems often have some of the best soil. With a proper variety of plant and animal species, our soil can constantly regenerate and produce enough microbes and nutrients to support all that lives on it.

Perseverance Rover: The Tech and Goals

Jim Bell, Arizona State University

Editor’s note: On Feb. 18, NASA’s Mars 2020 mission arrived at the red planet and successfully landed the Perseverance Rover on the surface. Jim Bell is a professor in the School of Earth and Space Exploration at Arizona State University and has worked on a number of Mars missions. He is the primary investigator leading a team in charge of one of the camera systems on Perseverance. We spoke with him in late January for The Conversation’s new podcast, The Conversation Weekly.

Mapping Cities’ Carbon Emissions Through Advanced Data Collection

As global emissions of greenhouse gas continue to rise, it is increasingly important for researchers and policymakers to identify exactly where and how much greenhouse gas is emitted and absorbed worldwide for global climate change mitigation. Over the past decade, Dr. Tomohiro Oda of the Universities Space Research Association (USRA) in Maryland has aimed to realize this need by combining emission data with night-time observations from satellites. Through this work, his team has now produced global maps that distinguish sources of carbon at unprecedented resolutions – high enough to identify variation across the regions where emissions are most intense: Earth’s cities.
