In poetry:

Ensam är du ej i cellen: tyst, osynlig, vid din sida
dväljs ett sändebud från honom, vid vars fot eoner bida.
Det är han, som styr din penna, där hon går så segerrik
för att rädda Platos himmel och Perikles' republik.
"I Klostercellen" by Abraham Viktor Rydberg

In science:

By pushing the MHD numerical simulations to their limits, Shafee et al. (2006) and Penna et al. (2010) calculated a thin, H/r . 0.1, disk-like accretion flow, and demonstrated that its inner edge torque is in fact small.
Slim accretion disks around black holes
The general relativistic MHD models that are currently in use (e.g., Penna et al. (2010)) often make use of dimensionless quantities and do not include detailed radiation transfer.

Abstract: This review deals with computer simulation of biological ageing, particularly with the Penna model of 1995.
The Penna Model of Biological Aging
Thus in the following chapters I review recent progress on the most widespread model of biological ageing, which was invented by Thadeu Penna before he was 30 years old (Penna 1995).
The Penna Model of Biological Aging
Fortunately, Altevolmer (1999) in between these biological observations simulated this plasticity in the Penna ageing model and found both decreases and increases of the minimum age of reproduction, depending on whether the predators kill mainly the young or mainly the old prey.
The Penna Model of Biological Aging
Thus simulations predicted some observations, and these observations do not contradict the mutation accumulation hypothesis in the Penna implementation.
The Penna Model of Biological Aging
It also appears in the Penna model, if the recombination rate (crossover probability) is not equal to one as traditionally but is much smaller.
