The solar system

The Big Bang was an explosion of the atom which at the same time matter became. This matter attach to each other forming stars, planets and all kinds of celestial bodies and particles attracting by gravity forms, shapes and weight.

The Milky Way is the constellation we are in the solar system and the hottest and coolest plates, but there are other constellations with solar system as well.

Have Money To Use

This looks like it would be a great app to use, I liked what I seen when getting ready to try to enjoy the app. But, I didn’t even get past the intro because you have to pay and only get three free days (usually is a week) and I am careful about apps and services that ask for card info. And for college students, which I am, we do not always have money and paying $10 a week for this app is not affordable. Looks like I’m on the search again for some useful apps.

Nursing Student

I absolutely love this app. Although I have long completed anatomy and physiology courses this has been a great way to keep up on vocabulary. Having a visual guide is extremely beneficial for those who learn better when they can see something in action. Thanks
