The JSqueak approach to accomplish this involved a lot of handwork for the byte handling. The objective of the image loading process is to read the bytes from the image file and reconstruct the objects they represent. The picture shows the structure of a Squeak Image containing the objects of the application (blue) as well as meta data (green). Thus it also contains all objects and data of the running application. But the image is not just one mega class file, it is a snapshot of the memory of a running application. Instead of having multiple class files containing algorithms and type description, everything resides in one file - the image. The concept of an image might sound strange for Java programmers, but has its advantages. It maintains a constant pressure inside the frying chamber to avoid leaks, to prevent the oil from sloshing around and to use less energy to heat the oil.In order to understand the image loading process we first take a look at the image concept and the image format. The experiment hardware is automated and closed for safety. The experiment measured the temperature of the boiling oil as well as temperatures inside the potato – three levels deep. The experiment captured the frying process with a high-speed, high-resolution camera to capture the bubble dynamics such as growth rate, size and distribution, as well as the escape velocity from the potato, the bubbles’ speed and direction of travel in the oil. The experiments were conducted on two ESA parabolic flight campaigns, whereby an aircraft flies in repeated arcs to recreate brief moments of weightlessness. To study how microgravity influences cooking techniques such as frying, a novel experimental carousel-type apparatus was designed to fly and be safe. High-speed video capture of steam bubbles in various levels of gravity from frying potatoes in oil – in an air-zero-g aircraft.
