W.M.'s Math & Physics Symbols GIFs

The following mathematical and physics symbols GIFs are designed to match the Times font as displayed by Netscape NavigatorTM or CommunicatorTM running on my Macintosh, but may differ in size on other systems or other browsers. The GIFs have transparent background, and are suitable for use with various background colours and images.

To download the GIFs, either brush the image with your mouse to activate the "Save this Image as..." facility of your browser, or click on the respective caption for individual display of the GIF which can then be downloaded by pressing on "Save As" of the topbar pulldown menu under "File".

The name of the GIF without the .gif ending is given in the caption. A red asterisk (*) after a caption indicates that the <IMG SRC="..."> command for the corresponding GIF should be imbedded in <SUB>...</SUB> to lower the position of the image below the text baseline.

Here are some oversized GIFs for use over the row borders:
S_qrt SQ_RT INT_gral circ_INT INT_GR_L C_RC_INT Sum S_UM
L_PAR R_PAR L_BRACK R_BRACK L_CURL R_CURL
The following GIFs are designed to be assembled into even larger symbols, of which the vertical extension can be increased either by inserting more than one strut, or by defining HEIGHT=... and WIDTH=... for the strut GIF(s):
      
LA_PAR
 






 
RA_PAR
         
LSTRUT
     
RSTRUT
         
LV_PAR

One problem arising in the use of these symbol GIFs is that the size relationship between font characters and GIFs differs from browser to browser, platform to platform, and hardware to hardware. Hence, something like (11) displays with the third "1" either larger or smaller than the first and second. The only way to avoid this seems to be to use GIFs for the other digits as well, and also for the parentheses. For this, the following additional GIFs are available, as e.g. in:

1.gif 2.gif 3.gif 4.gif 5.gif 6.gif 7.gif 8.gif 9.gif 0.gif
lpar.gif rpar.gif lcurl.gif rcurl.gif

Some boldface analogs in the same size and larger have been added for use in titles. They allow composing sets of indices such as e.g. the following:
 

1bf.gif 2bf.gif 3bf.gif 4bf.gif 5bf.gif 6bf.gif 7bf.gif 8bf.gif 9bf.gif 0bf.gif
 
bar1bf.gif bar2bf.gif bar3bf.gif bar4bf.gif bar5bf.gif bar7bf.gif   lparbf.gif rparbf.gif
1_BF.gif 2_BF.gif 3_BF.gif 0_BF.gif bar1_BF.gif bar2_BF.gif bar3_BF.gif L_parbf.gif R_parbf.gif

 

NOTICE: Be sure to download the symbol GIFs to your site first, before calling them up in <IMG SRC="..."> declarations on your Web page(s).
Do not under any circumstances place paths in such declarations to GIFs on this site, but always download the GIFs you wish to use to your site first.
