Uses. Minols have historically been used in four types of ordnance, a) underwater (mines, torpedoes and depth charges) where the confinement of water offsets some of the loss of detonation velocity, b) blockbuster bombs in which a sustained and powerful impulse is more destructive than a high peak press, c) concrete fragmentation bombs where the high impulse will impart a satisfactory fragment velocity but will not pulverize the concrete they contact on impact, and d) in general purpose (GP) bombs...

In fact, the material is pressed at such a high temperature that explosive ingredients particularly sensitive to friction and impact such as nitroglycerine and nitrocellulose may be exploded by a minute initiating thermal or mechanical impulse. 

In the above fig of a typical blast wave, peak pressure is the press increase at the shock front or the highest press in the wave minus atmospheric press, and is a measure of the max force exerted by the blast wave. Impulse is mathematically equal to rhe positive phase and is a measure of the force multiplied by the duration. The negative phase iasts considerably longer than the positive phase but the max negative press is only a fraction of the max positive press (See Ref 12,p 65ff)... 

In general, both peak press and impulse must exceed certain min values in order to demolish various structures. Structures that are strong... 

Various improvements in the design of air blast meters were made possible by the use of piezo-elec gages, tourmaline gages and Pb or Cu crusher cylinders with suitable electronic amplifying devices. It is possible with these devices to obtain complete detailed records of the shock wave and to compare peak press and impulse values of different expls. These blast meters are described in various refs(Refs 2,3,4,5 9a). Schmidt(Ref 9) discusses various experimental procedures used for measuring blast effects...

Other reports emphasize the importance of charge geometry in the detonation process. An empirical equation relates the specific impulse (see Vol 4, D394-L) of TNT disks to sample dimensions (Ref 138). The reaction time of pressed TNT is less than half of that of the cast material (Ref 122) these measurements were... 

The central point within our consciousness, our "spirit" in the hermetic sense, can now be seen as an entity that can work to control quantum probabilities. To our "spirits" our brain is a quantum sea providing a rich realm in which it can incarnate and manifest patterns down into the electrical/chemical impulses of the nervous system. (It has been calculated that the number of interconnections existing in our brains far exceeds the number of atoms in the whole universe - so in this sense the microcosm truly mirrors the macrocosm ). Our "spirit" can through quantum borrowing momentarily press a certain order into this sea and this manifests as a thought, emotion, etc. Such an ordered state can only exist momentarily, before our spirit or point of consciousness is forced to jump and move to other regions of the brain, where at that moment the pattern of probability waves for the particles in these nerve cells, can reflect the form that our spirit is trying to work with.
