The Mathematics of Popcorn
A kernel of popping corn consists of a hard outer shell called the pericarp which is impermeable to moisture and a dense center filled with starch, water and some oil[8]. As the kernel is heated, internal pressure rises to approximately 135 psi, at which point the pericarp bursts. The steam and starch expands to a foam which rapidly cools forming the popcorn. Variations in the strength of the p...
متن کاملControlling the Size of Popcorn
We present a thermo-statistical model of popcorn production and propose a way to control the final size of the popcorn by monitoring only the chamber pressure. P.A.C.S: 05.20-y, 01.55.+b, 01.90+g, 05.70-2. How can one control the size of popcorn? The food industry may have ample reason to seek for ways to double or triple the size of popcorn, because large popcorn may be pleasing to the eyes, p...

Cerebral cavernous are vascular lesions defined by the presence of deformed capillaries without interposition of nervous tissue. These are relatively rare (0.1 to 0.5% of the general population and less than 5% are symptomatic), clinical symptomatology is dominated by hemorrhage and epilepsy, and also depends on the location. Cerebral MRI is the gold standard for diagnosis, therapeutic approach...
متن کاملBag of Words Meets Bags of Popcorn
‘ This problem is selected from one of the Kaggle’s competitions [2]. In this problem, we dig a little ”deeper” into sentiment analysis. Word2Vec is a deep-learning inspired method that focuses on the meaning of words. Word2Vec [3] attempts to understand meaning and semantic relationships among words. It works in a way that is similar to deep approaches, such as recurrent neural nets or deep ne...
متن کاملPopcorn: critical temperature, jump and sound.
Popcorn bursts open, jumps and emits a 'pop' sound in some hundredths of a second. The physical origin of these three observations remains unclear in the literature. We show that the critical temperature 180°C at which almost all of popcorn pops is consistent with an elementary pressure vessel scenario. We observe that popcorn jumps with a 'leg' of starch which is compressed on the ground. As a...
